Part of the problem is, the mRNA vaccines (Moderna, Pfizer) are coming out as superior to the adenovirus-vector based vaccines (AZ, J&J) both in terms of efficacy and safety.
Everyone needs to weigh up their own risk-benefit ratio. Neither the government, nor most doctors, have time to do this for you. If you choose to refuse AZ (or Vaxzevria, as it has now been rebranded) that should be based on your own valid concerns. The problem is that the information being provided to us by the UK government / MHRA etc. has been somewhat skewed in order to reassure everyone. This is understandable. Whichever way you look at it, the risk for most people is very small. But it still exists. And risk has to be looked at in context. (Incidentally, comparing it to the risk for the pill is a non-starter because there is a choice of contraception available. We are not being offered a choice of different vaccines.)
Take a look at the statistics given in the press conference. The "one death in a million" made a nice soundbite but it didn't help a younger person work out their own risk because the vast majority of people vaccinated in the UK so far with AZ have been OLDER people. What they should have done is told us, for example, how many thirtysomethings have developed the condition as a percentage of how many had actually been vaccinated with AZ. And remember the risk-benefit graph with coloured splodges representing how many people would die of Covid versus the AZ vaccine? It was divided by age group - but didn't separate out the clinically vulnerable from the healthy. We know that the risk of dying of Covid for a healthy 35-year-old is far smaller than the risk of dying of Covid for a 35-year-old with, for example, diabetes or kidney failure. The 30-39 group still to be vaccinated is the healthy 30-39 group - that's why they are still to be vaccinated. So the risk figures should have been directed specifically at them. Same argument goes for the 40-49 age group, incidentally.
In weighing up risk, you can also take into account whether you have already had Covid. You will likely still have antibodies up to six months afterwards (you could take an antibody test to be sure). However, some new variants can get around natural immunity just as they can get around the vaccines. Overall, most people will STILL be better off getting the vaccine. Should our government have done what other countries have done and NOT placed the responsibility for working out individual risk on the shoulders of individual 30 and 40-somethings? Should it have been more transparent in the information it has released? Should the government have slowed down the lifting of restrictions to get in other vaccines and thereby save the lives of a few healthy young(ish) people? Or should the government not have relied so heavily on one particular vaccine when other countries didn't?
