The Pfizer vaccine needs to undergo secondary analysis.
It needs to be stored in a -80 freezer. Pfizer says 50 million vaccine doses in 2020 and up to 1.3 billion doses in 2021. takes 4.Weeks to develop immunity. Only 1.35 billion doses, everyone needs two so only what 653 million people can get vaccinated by the end of 2021? That’s a fraction of the population. And how many vaccines are going to your country or state? And how will they be prioritized?
I am sorry, I know this forum likes to hope that things will go back to normal but it will take years to vaccinate and we will be wearing masks until then.
Let’s just hope the vaccine gives long term immunity because we are seeing multiple reinfections here.
