It is very hard to tell the difference between Covid and a cold without testing
Before the Covid-19 pandemic, if you got a sniffle and a headache, you might dismiss it as an ordinary cold and carry on as normal, even if you felt a little rough around the edges. But during cold and flu season, how can you be sure it’s a cold and not the coronavirus?
The common cold is caused by a different strain of virus to Covid-19. But with the rapidly-spreading Omicron variant often causing mild symptoms, such as stuffy nose, sore head and sore throat, it is very hard to tell the difference without testing.
The real-world study includes data on positive Covid PCR test results between May and July 2021 among more than a million people who had received two doses of Pfizer or AstraZeneca vaccine.
Protection after two shots of Pfizer decreased from 88% at one month to 74% at five to six months.
For AstraZeneca, the fall was from 77% to 67% at four to five months.
Official data is ‘exaggerating’ the risk of Covid-19 and talk of a second wave is ‘misleading’, nearly 500 academics told Boris Johnson in open letter attacking lockdown.
The doctors and scientists said the Government’s response to the coronavirus pandemic has become ‘disproportionate’ and that mass testing has distorted the risk of the virus.
