If you are asking about an allergic reaction, they usually occur within minutes of receipt of the injection or within the hour afterward. This is one reason that the newest guidelines say that some people with Allergies to the traces of egg in the vaccine can get the vaccination anyway, as long as they are monitored closely afterward. See the related question below for more on that.
If you are asking about a reaction like the local irritation, tenderness, and redness at the site of the injection, those are usually noticed the next day and will go away typically in 3 days or so after. That type of inflammatory reaction is not an allergic response, it is part of the process our bodies use to attack foreign substances that have invaded our bodies.

Why does it take 3 months until you find out hiv in your blood?
Because your body takes time to develop antibodies. Modern HIV tests (called fourth generation tests) can detect 95% of infections by about four weeks.
How much time it takes to produce detectable antibodies in the blood during primary immune response?
In general, it takes approximately one week(or less than a week) for an adult to develop antibodies during primary immune response.
How long does an active immunity take to develop?
Active immunity typically takes several weeks to develop after exposure to a pathogen or vaccination. This process involves the immune system recognizing the antigen, producing specific antibodies, and generating memory cells for future protection. The exact timeframe can vary depending on the individual and the type of pathogen or vaccine involved. Generally, it can take anywhere from a few days to a few weeks for active immunity to become fully effective.
Why are babies not born with immunity acquired by parents through infection or vaccination?
Actually babies are born with some antibodies from the mother, and will acquire more as long as the baby breastfeeds.
How long do antibodies live?
As long as they are an otherwise healthy person, they last for life. However, cold and flu viruses do mutate readily. There are no vaccines for the common cold, and since they mutate so quickly and frequently, antibodies for the original cold would be obsolete very soon after you recover and other colds will be able to continue to infect you. Similarly, a new modified version of the flu you had (or vaccination you had) may not be affected by the antibodies like the original version was. In that case without a vaccination for that new type (or without having the new or a very similar infection), then you would have to get an exposure or vaccination for the new version to be able to have antibodies that are effective to gain immunization to the new one. As long as the virus is the same virus (exactly) that you had or that you were vaccinated for, then the immunity is lifetime.
How long until dtap vaccine takes effect in adults?
The DTaP vaccine, which protects against diphtheria, tetanus, and pertussis, is typically administered in childhood, but adults can receive the Tdap booster. After vaccination, it generally takes about 1-2 weeks for the immune response to develop and provide protection. However, full immunity may take a bit longer as the body builds up sufficient antibodies. It's important to stay up-to-date with booster shots every 10 years to maintain immunity.

How long is a macaw's gestation period?

Why does passive immunity usually not last for long?
When you have immunity, your body has antibodies against a foreign organisms (i.e. bacteria and virus) . Usually this is achieved by exposure to these organisms. That is: 1. you get an infection (or vaccination with inactive parts of a bacteria or virus), 2.your body defeats the invader, 3. some of the cells in your body "remember" which antibodies they produced , 4. next time you are exposed to the same foreign organism, these cells quickly produce antibodies so you won´t get ill (i.e. you are immune) When you have passive immunity, it usually is due to a vaccination with antibodies. Your body hasn´t produced the antibodies on its own. So once the antibodies become too old and inactive, you are not immune any longer, and when you encounter the foreign organism again, it will be like a novel infection, because it has no memory cells, which can respond quickly.
How long does it take for the symptoms of tuberculoid leprosy to develop?
On an average, it takes four years for the symptoms of tuberculoid leprosy to develop.
