How many 3 tsp doses are in 500 mL?
64 doses
Just divide the 34 by 0.00055. So 34 / 0.00055 = 61818 doses.
1 mg = 1 000 μg The answer is 5 000/3 = 1 666 doses

India started vaccination against polio in the year 1978 with Expanded Program in Immunization (EPI). The vaccination is done by giving three doses of OPV to each infant and by 1984 Government of India was successful in giving vaccination to almost 40% of the infants in the country. Universal Immunization Program (UIP) was introduced to cover all the districts of the country in the year 1985. Many programs have been launched by the Government of India to completely eradicate polio from the country. Pulse polio campaign was established in the year 1995-96 by the Government of India.
Toxoids are inactivated toxins from pathogens. They are used to stimulate the production of antibodies. Though many pathogens are not harmful themselves, the toxins they are produce cause sickness. Toxoids can be used to protect the body against such illnesses. Both tetanus and diphtheria immunization use toxoids.
There are no exact figures, but, as the most common serious side effect is due to a allergic reaction to the vaccine, and that reaction occurs less than 1 time per million doses administered, the number of fatalities directly due to the vaccine itself is extremely small. The OPV (activated polio virus) causes polio just over 2 in a million times. The IPV (inactivated polio virus) does not cause polio at all. IPV is now the standard vaccine given in countries where polio is no longer present - OPV is the standard where polio is still endemic (as it is a bit more effective than the IPV in promoting resistance). Overall, in the 50+ year history of the various polio vaccines, I would estimate that the total number of deaths linked to the vaccine number in the low hundreds, almost all of them due to uncontrolled allergic reactions. Which is a very low risk, considering that upwards of 20 billion vaccines have been given.
Polio was one of the most dreaded childhood diseases of the 20th Century in the United States. There were usually about 13,000 to 20,000 cases of paralytic polio reported each year in the US before the introduction of Salk inactivated polio vaccine (IPV) in 1955. Polio peaked in 1952 when there were more than 21,000 reported cases. The number of cases of polio decreased dramatically following introduction of the vaccine and the development of a national vaccination program. In 1965, only 61 cases of paralytic polio were reported compared to 2,525 cases reported cases just five years earlier in 1960.
50,000 people died of polio.

A polio vaccine was invented in 1954. Each year after that, the number of polio cases decreased. By 1974, only 5 cases occurred. These were all people who were linked to the polio vaccine.
