There’s some evidence that the booster is necessary so quickly because the first 2 doses are being given so close together in an effort to give a high degree of immunity quickly in an effort to slow the pandemic. Some scientists argue that if the second dose was administered several months later that immunity would last longer, but it also means people wouldn’t be as well protected while they wait for the second dose. However, UK and Canada (IIRC) spaced their doses (12 weeks?) and I’m pretty sure they’re also giving boosters, so I can’t say what the optimal strategy is at this point. I’ll just keep getting boosters when recommended and maintain all precautions within reason.Are the 1 shot Pfizer and Moderna boosters as effective as the first 2 doses combined? or is it just basically a third shot?
Wouldn't this just be giving you 50% of the protection that the 2 doses give you? Why aren't boosters just another 2 dose round for max effectiveness? This gives me the feeling that we're going to be right back here in 6 months needing another booster.
