I just read this: https://www.reuters.com/article/factcheck-pfizer-vaccine-tra... > The same presentation slide describes “Other benefits likely uncertain at approval and only clearer after the vaccine is used” to include the vaccine’s “long term protection,” “prevention of infection (asymptomatic cases),” and “prevention of virus transmission in the community - needs specific studies post-approval necessary to show.” This implies they only checked it reduces symptoms in affected. Transmission prevention and long term immunity would be tested at later point. So what was then the point of getting everyone vaccinated? Weren't vaccines supposed to contain its spread? When I got vaccinated for various diseases, it gave long term immunity, not 4 doses over months to lessen the symptoms. |
Please double check yours. There's a few common vaccines that people assume are "life long" but actually have a recommendation for boosters when you're an adult.
But yeah, in general the length of immunity differs, some vaccines work forever, some not. It's a limitation of what we can produce.

Multiple reasons. Prevent many deaths, lower symptoms, make recover easier, lower emergency departments load, lower transmission, etc. None of those were going to be perfect or work independently of people's behaviours.
