Two weeks after receiving the first dose of the vaccine for Sars-CoV-2 (the name of the virus causing COVID-19), I tested positive for the virus. This was probably not because of the vaccine but because I was infected with the virus. Remember, vaccines are not 100% effective, and they can take about 4 weeks to begin to have an effect in most cases. Instead of only sending off a sample to a lab which can take a few days, in my workplace, we use a lateral flow test, which gives a quick result (within 30 minutes). Here we will go through the test and how it works.
In January, around 2 million people in the UK had received ate least the first dose of their vaccine against SARS-COV2, the virus that causes COVID-19. As of 11th March 2021, that figure had risen to more than 23 million people, about a third of the UK population. Tom had his vaccine in January, and you can read a little more about his experience here.
