What is pneumococcal vaccine 23?
PNEUMOVAX®23 (Pneumococcal Vaccine Polyvalent) is a vaccine indicated for active immunization for the prevention of pneumococcal disease caused by the 23 serotypes contained in the vaccine (1, 2, 3, 4, 5, 6B, 7F, 8, 9N, 9V, 10A, 11A, 12F, 14, 15B, 17F, 18C, 19F, 19A, 20, 22F, 23F, and 33F).
The main difference between the two is the amount of bacteria that the vaccine can help protect against. Pneumovax 23 protects against 23 types of pneumococcal bacteria, while Prevnar 13 protects against 13 types of pneumococcal bacteria.
- CDC recommends pneumococcal polysaccharide vaccine for all adults 65 years or older, people 2 through 64 years old with certain medical conditions, and adults 19 through 64 years old who smoke cigarettes.
- The first pneumococcal vaccine, licensed in 1977, was a polysaccharide vaccine. It contained purified capsular polysaccharide antigen from 14 different types of pneumococcal bacteria. In 1983, a 23-valent polysaccharide was licensed (PPSV23; Pneumovax, Merck). It replaced the 14-valent vaccine.
- Four types of vaccines are currently available: Live virus vaccines use the weakened (attenuated) form of the virus. The measles, mumps, and rubella (MMR) vaccine and the varicella (chickenpox) vaccine are examples.
Pneumovax 23 (Pneumococcal Vaccine Polyvalent) is a vaccine that helps protect against serious infection, such as ear infection, sinus infection, pneumonia, blood infection (bacteremia), and meningitis (infection of the covering of the brain) due to the bacteria Streptococcus pneumoniae.
- Pneumococcal Vaccine Side Effects. Pneumococcal vaccines are very safe and effective at preventing pneumococcal disease. Vaccines, like any medicine, can have side effects.
- The main difference between the two is the amount of bacteria that the vaccine can help protect against. Pneumovax 23 protects against 23 types of pneumococcal bacteria, while Prevnar 13 protects against 13 types of pneumococcal bacteria.
- You Can Get Influenza and Either Pneumococcal Vaccine at the Same Time. You can get either pneumococcal vaccine (but not both) when you get the influenza (flu) vaccine. While you don't need a pneumococcal vaccine every year, it is important to get a flu vaccine each flu season.
These 23 types cause about 9 out of every 10 infections caused by pneumococcus bacteria. The vaccine is inactivated, which means that it does not contain any live pneumococcal bacteria. It cannot cause pneumococcal disease. In the UK, PPV is given to adults aged 65 and over.
- 2. Killed-inactivated vaccines. To produce this type of vaccines, bacteria or viruses are killed or inactivated by a chemical treatment or heat. This group includes for example the inactivated poliovirus (IPV) vaccine, pertussis vaccine, rabies vaccine, or hepatitis A virus vaccine.
- The BCG vaccine contains live bacteria that have been weakened (attenuated), so that they stimulate the immune system but do not cause disease in healthy people.
- The nasal spray flu vaccine does contain live viruses. However, the viruses are attenuated (weakened), and therefore cannot cause flu illness. The weakened viruses are cold-adapted, which means they are designed to only cause infection at the cooler temperatures found within the nose.
