re: Covid vaccine check in

Pride a couple of questions.

1) has the length of antobody life in covid patients been further studied? I mean I’m sure it has but are they still saying 3 months likely?

2) when would you expect science to be able to tell us if this will be a yearly vaccine that needs to be repeated

Thanks — not sure you can answer but surely someone can!

I'm young.. ish, healthy, in shape, and take no medications. I have the opportunity to take the vaccine this week and I am doing it. I feel selfish because there are people in my Community that are more at risk that have not had the chance to get it.
