Vaccinations

A vaccine is the preparation of dead microorganisms, living weakened microorganisms or inactivated toxins. Its administration induces the development of immunity and protection against a pathogen or toxin and is called a vaccination.

Where and how do you get MMR vaccine as separate vaccines for each disease instead of the combined vaccine for MMR are these vaccines available separately by any manufacturers?

Separate vaccines are no longer on the market in the US as of spring 2015. There is no medical reason to separate these vaccines. Talk with your health care provider for accurate information about the risks and benefits of MMR vaccination.

Does the US 2012-2013 flu vaccine contain swine flu vaccine?

This year's vaccine does contain Type A, H1N1/09 vaccine made from the specific type (i.e., mutation) of the H1N1/09 virus that is expected to circulate in the US in flu season this year. That specific strain is called:

A/California/7/2009 (H1N1)pdm09-like virus

The vaccines made from the other two selected influenza strains that are in the 2012-2013 flu vaccines in the US contain:

A/Victoria/361/2011 (H3N2)-like virus

B/Wisconsin/1/2010-like virus (from the B/Yamagata lineage of viruses)

Who came up with the vaccine?

Jonas Salk came up with the first injectable polio vaccine, followed by Albert Sabin who came up with the first oral polio vaccine.

Who discovered bcg vaccine?

Bacille Calmette-Guerin (names of two French scientistswho prepared this vaccine)

Can you Explain the live virus in vaccines?

Vaccines are small amounts of live viruses injected into the body. These viruses teach the body's immune system how to fight off the disease.

Correction: Some viruses are live. Some are weakened, most flu vaccines are dead viruses, not live, although the nasal mist is a live, weakened virus. Please make sure your answers are correct.

Why do toxins need to be inactivated before being used in vaccines?

A toxin is a poisonous substance produced by living cells or organisms. Toxins produced by microorganism are important virulence determinants responsible for microbial pathogencity and/or evasion the host immune response. This will alter the human physiology when taken so to avoid the bad effect of toxin it is first inactivated and then used as vaccine which is known as toxoid.

Can a flu shot cause cellulitis?

Yes, there can be a local infection from a contaminated needle from a flu shot and that would be called cellulitis. However, many people can get a red, sore, slightly swollen area at the flu injection site from the desired immune response. This usually goes away in a few days. It gets better from exercising the muscle into which the shot was injected. If it is more than two days after the shot and the redness or inflammation is still increasing, then you should seek advice from your health care professional.

Why are children given vaccination?

Children are given vaccinations to develop antibodies against various diseases so that they are less likely to become seriously ill. Many diseases have been eradicated (stopped) through the decades of vaccinations of babies and young children. However, when parents didn't have their babies and toddlers vaccinated, many of these awful and deadly diseases have begun to re-appear.

How peptide based vaccines are helping to give immunity than full length genome?

The immune system recognizes antigens present within infectious organisms/viral particles/tumor cells. These antigens are typically proteins, but can be complexed with lipids or carbohydrates. Nucleic acids can be targeted by the immune system, but they are not distinct enough to act as appropriate antigens.

Do you need a tetanus vaccine for razor cut?

It depends mainly on where the razor was used and how serious the cut is. for example if the razor has been anywhere where there may have been harmful bacteria.

Is it normal for a tetanus shot to cause an arm to get kind of swollen and have red discoloration I got one a few days ago my arm is killing me and have a few days till I see a doctor again?

Yes, as long as it is small and local just to a small area at the injection site. If it has spread more than an inch or 2 beyond, call the doctor as you may have had a bad reaction. Many people get a mild reaction that results in swelling, discoloration, and even a "lump" that can last for weeks and this is not unusual.

What inoculations are needed for the Caribbean?

It depends on what country in the Caribbean you're traveling to. In the Dominican Republic, for example, you need the routine vaccinations (which you likely already have), plus Hep A and B, typhoid, and Rabies. See the website for the Centers for Disease Control and Prevention (CDC) for the list of advisories for each country.

How much does a shot or a vaccination hurt on the arm- compare the pain to something like a bug bite or a gun shot?

On a scale of 1 to 10 with 10 being the worst pain ever, it is probably almost always less than 1. I would liken it to a prick from a thorn or splinter, or more than a bug bite but less than a bee sting or similar to poking yourself with a sewing needle or straight pin by accident.

It can vary depending on what medicine is in the shot, some medicines sting or burn as they are going in (it helps if they are injected slowly). Thick medicines also hurt more and slow injection also helps prevent that. But these two circumstances still would be less than 1 on the pain scale in most cases.

If the medicine is not an irritant to tissue and if the injection is done correctly, you may not even feel it. If you feel it, it lasts only a second or two just as the needle goes in. Count, "1 Mississippi, 2 Mississippi, ... " and see how fast it goes.

Influenza vaccinations, for example, are given in small quantities and the needles used are not very big when injecting into the muscle as most flu shots are. There are even smaller (90% smaller) needles used when you get the newest intradermal vaccines. They go into the layers of the skin, not as deep as muscle or subcutaneous injections. They are good for those with needle phobias and, these almost never hurt.

Sometimes some people will get a sore arm the next day from vaccinations. It can feel like a strained muscle and might be very sore to the touch, have reddish skin and be slightly swollen. This is a normal reaction to the immune response that the vaccine is causing, and it is noticed more at the local site of the injection at first. It should go away in a matter of days and the more you use your arm, the faster that will improve.

Shots in the arm are really usually no big deal.

Do k1 visa holders have to comply with the vaccinations?

Yes, eventually they do. But, sometimes it is much less expensive if they get them in their ouwn country before coming to the US especially if their countries have universal health care.

What are solutions of killed or weakened viruses?

One such example would be a vaccine for viral illnesses. They can be made from attenuated (weakened) viruses or from inactivated viruses or pieces of them.

How long does the smallpox vaccination last?

Vaccination effect of the small pox last for life time. You need to consider vaccinating the whole population against the small pox. It gives some protection against the HIV infection, probably.

provider!

Can you get the flu from someone who just got a flu shot and got sick from it?

It isn't possible for a flu shot to give someone the flu. The shot is made from inactive ("dead") virus particles that can not cause infection. They just provide the "pattern" of that particular virus strain to cause your immune system to react by making the right antibodies that will "kill" the same strain (pattern) of flu if a "live" particle ever does enter your body.

It is unlikely, but possible, for the flu vaccine that is given in a nasal spray to cause the flu in someone who has a very weak or compromised immune system, such as due to HIV/AIDS, or chemotherapy, for example. The vaccine for use with the nasal administration is made from active virus particles that have been weakened so they won't be strong enough to cause infections, except in extremely rare situations in a specific demographic group.

However, people in close association and physical contact with the person who got the nasal spray vaccine could also, theoretically, get the flu from exposure to that "live" virus in the nasal spray, so precautions are recommended for those people with poorly functioning immune systems to avoid close contact with someone who has just had the nasal vaccine (they should only use flu shots and are not supposed to take the nasal type of vaccinations themselves either).

When you get a flu shot, it can take your body two weeks before you develop full immunity. If you were around someone who had the flu after getting a flu shot, they probably either had a different strain of flu than was included in the vaccine; or they were already infected immediately before getting the shot, but had not yet shown the symptoms; or they caught the virus between the time they got the shot and when their body had developed the full immunity.

If any of the last three scenarios occurred, then you would be able to catch that flu from them.

See the related question below, "If you had the flu shot and you get the flu what happened?" about what might have happened if you had the flu vaccination but still got the flu, for more details of the possible, but unusual circumstances, that could allow this to occur.

If you have the flu already will a flu shot work?

The flu shots are to prevent the flu, not to treat the flu.

It will not be necessary to get a flu shot after you have had the flu, if you know what type of flu you had for sure (by lab testing). If you are not sure that it was the seasonal flu or another type of flu (like swine flu), then taking a vaccination will be a good idea to be sure you are protected for the other strains of flu. It will not hurt to take a flu shot for the same type of flu you had, and if the vaccine is for a different type, then you will have that added protection. You should usually wait until after the symptoms of active fever are gone before getting a flu shot, though.

Flu shots work by exposing you to a small amount of weakened or dead viruses that cause a specific flu, or sometimes the vaccine will cover several (the seasonal flu vaccine usually contains three strains), so that your body can build immunity to them before being exposed to the full strength viruses in the environment.

For the 2009 - 2010 flu season in the US, you are encouraged to get two vaccinations for the flu. One for the seasonal flu (it protects against three flu strains) and one for the A-H1N1/09 swine flu. If you have not had lab confirmation of the type of flu you already have had, then the CDC still recommends you get both vaccines.
