@earl said in [Coronavirus Outbreak](/post/1449745) said:Interestingly with the data that has been provided there has been some analysis of Pfizer versus AZ.
The big picture remains the same in that the efectiveness of both vaccines is very very similar.
I'll add a slight bit of information to this picture but it's not worth focusing on in relation to getting vaccinated. The Pfizer vaccine appears to have a better initial rate of effectiveness but this decreases over time whereas the AZ vaccine appears to have a lower initial rate of effectiveness but this increases over time. There could be more to this picture because this could be due to the time period between your first and second dose.
Interestingly Dr Chant mentioned the initial dosing time frame in the press conference yesterday. She wants everyone double dosed even though there is a possibility this leads to a decrease in effectiveness over time. She stated that this will be mitigated against via booster shots.
Read the same Pfizer is running out of puff against Delta while AZ is staying stronger and lasting longer against Delta ..
