It is possible indeed that the Pfizer vaccine is not particularly efficient against Delta but, at the same time, Israel is only one country among a growing list of countries facing a new wave of Covid and what we can see over there does not show up (yet?) in other countries such as the UK or France.

Even if Dr Haviv is correct and the protection offered by the Pfizer vaccine is only valid for 7/8 months, many lives have still been saved in the meantime (Israel got almost no cases and deaths in Q2 2021 for example).

I guess more data is required to see how it goes but it is ackowledged that not all the vaccines have lifetime effects and some only work against specific variant (like the flu one).

To finish, I would like to reiterate that the Delta variant is a game changer so a quote from February needs to be taken with a grain of salt because the situation has changed completely since then.
