Recently, as the news about COVID vaccine is everywhere, I'm seeing some similar stuff on many sites like "we will need yearly vaccine like other vaccines", "we would need covid vaccine like flu vaccine", "measles vaccine" etc.
Now the purpose of this question is not to discuss anything about COVID.
The thing is, I was born in a village life. People know very less stuff about health and vaccination. One common vaccine I know is of Polio. I don't know about any other vaccines.
So my question is, do we need other vaccines apart from Polio after birth and do we need to take them again after a certain time? This question came to my mind because I heard nobody near me going for vaccination after their childhood is over.
And I got intrigued very much because I read measles is airborne (something like that) and vaccination is the cure. And flu/influenza also needs vaccination. So I'm really really confused.
