How will you feel when you have been given a Covid-19 shot?

People around the world are becoming excited at the news that vaccines which may stop the currently rampant Covid-19 virus will soon be available for mass inoculation programmes.

China has a vaccine it has been testing with several countries including Brazil.

Then the US and Germany announced that Pfizer has produced a vaccine that is 90% effective and will be widely available soon.

And now, as Russian pharma developers try to keep pace with Western drug makers in the race for a shot, Moscow announced on Wednesday that its Sputnik V vaccine is 92% effective at protecting people from Covid-19 in interim trial results.

Everyone will be keen to be given the shot and protect themselves and those around them as soon as possible.

But how does it feel when you have been injected with the vaccine?

Some volunteers who took part in Pfizer’s coronavirus vaccine trials say they were left feeling like they had a severe hangover, according to reports.

More than 43,500 people in six countries took part in Pfizer’s phase three trials. They were never told whether they had been injected with the vaccine or a placebo in the double-blind tests.

Some said they believe they were given the drug because of headaches, fever and muscle aches that were compared to getting the flu shot or recovering from a heavy night out, the Sun said.

Texan Glenn Deshields, 44, said his “severe hangover” symptoms soon cleared up, however, and he later took an antibody test that came back positive. He said he was “very excited” by news that the tests showed the vaccine was 90% effective.  “Thank God, it’s going to be over at some point,” he said.

Another volunteer who only gave her first name, Carrie, said she suffered a headache, fever and aches all over her body after her first shot – symptoms that were even more severe after the second one, Metro UK said. The 45-year-old from Missouri said taking part in the trials was her “civic duty”.

“There are so many people who have had Covid and suffered. The thought that we could do something to stop people from suffering from this, from losing family members, that we could get rid of it and get back to some sort of normal in our lives – that’s a driving factor for this for me,” she said. “I don’t want anyone else to be sick.”
