MMR also requires boosters, as does Pneuomococcal. HPV and Meningococcal C are too new to tell, but most likely will later be determined to need boosters(which is what happend to MMR and Pneuomo). Polio also requires a booster, but because it's been eradicated in the US for decades they only require it if you travel, particularly to Isreal, Gaza, and the West Bank. Rotavirus probably would require boosters, but it's a disease that isn't dangerous in adults so they don't require one. Hep C has shown itself to be effective after 10 years, and so may be one of the few that don't require boosters.WolfThomas said:It really depends on the vaccine. You need a booster for tetanus if you're exposed and havent had one for 10years and whooping cough has a booster in the 50-60s for most countries. Flu vaccine is new every year. Hep B immunity is something you can lose too.spartan231490 said:actually not really. Vaccines are not permanently effective. Technically speaking, you need to get boosters for most of them every 8-10 years if you want to keep your immunity. This is actually a point of great concern for some diseases because it has resulted in a large and growing portion of the public with no immunity to these diseases. Most of which are worse if you contract them as an adult.WolfThomas said:There's a bit of a difference between the flu vaccine and the immunisation schedule most countries have for children.
Most people by adulthood are immune to a large number of previously potentially deadly diseases such as polio, measles, whooping cough etc. Because of vaccines.
However with a lot like HPV, Measles, Mumps, Rubella, Polio, Rotavirus, Pneuomococcal, Meningococcal Group C etc once you've done the required amount you're immune for life.
Still vaccines are awesome. Have saved more lives than any other medical intervention.
And Yes, vaccines are a good thing, but most of them are not permanently effective without boosters. All vaccines are initially marketed as being permanent, and almost all of them eventually turn out to be not permanent. This doesn't mean they aren't a good thing, just that the adult population needs to be more aware of boosters if we want to maintain an immune population.
