On April 7th 2021 the UK regulator recommended against delivering the Oxford AstraZeneca vaccine (AZ vaccine) to those under-30 if an alternative vaccine could be offered instead. The news followed deaths arising from blood clots and a suspension of use of the AZ vaccine by various other countries. The story became headline news and online search querying vaccine safety increased. What happened to Covid-19 vaccine intentions and attitudes? I collected relevant data the day after the story hit the front page. I asked UK adults if they intended to get the vaccine and measured their attitudes towards it (after revision period: n = 502). I compare these data against two previous waves that used precisely the same methods of data collection (see Comerford et al., 2021). The first was taken before stories linking the AZ vaccine to bloodclots had been reported (baseline period: March 12th -15th ; n = 241). The second was taken after the AZ bloodclot story led EU countries to suspend use of the vaccine but before UK regulator changed guidance (before revision period: March 17th ; n = 305). The data show no change in intentions or attitudes in the sample as a whole, nor in the subgroups who we would expect to be most affected by the UK regulators’ guidance (under-30s and those aged 30–40).
