Vaccines required in Costa Rica

I am no longer subscribing to this thread. Tired of reading people saying they won't help stop this pandemic by wearing masks, social distancing or vaccinating.
There's no point trying to convince people when they have their mind made up to NOT follow scientific recommendations re a pandemic.
I don't get it at all, it's mind boggling to me. But so be it. I'm done with talking about it here.

I am very concerned about the elderly all over the World who received the mRNA vaccines i.e. Moderna and Pfizer.  I am afraid we will start seeing one  of two things.......  Shots yearly as boosters OR New vaccines due to the number of Variants.  I have elderly neighbors who without thinking waited up to 5 hours in line to receive a vaccine.  Not one that I have spoken to had any reservations about not receiving the shot.  I understand that when one is elderly or has an underlying medical issue they are terrified of  having Covid and this pushes them into taking these decisions. 

When the Science of a new vaccine convinces me otherwise I will get the shot.
