Dear Mr. Vidal!

You raised a critical point. At the moment this is a question they research all over the world. There are many factors at play as this is a case - and context dependent matter:

May I argue one should not focus on evaluating the length of protecting effect but having a safe, healthy life without worrying too much. Covid-19 variants and further mutations will change the landscape anyway. Yours sincerely, Bulcsu Szekely

It is too soon to know how long a vaccine will last. It is currently being researched. Of the people who have received the vaccine, we know that they have been protected from COVID-19 for at least 4 months

also, better to check this out.
