It has recently been revealed that important steps have been taken to change the game in the fight against Covid. A vaccine from Pfizer could end the pandemic. The vaccine is considered to be “more than 90% more effective”, which brings optimism around the world that a sense of normalcy could be closer than I thought in the last nine months.
To date, the UK has provided 30 million doses of vaccine – enough to vaccinate those considered at higher risk of infection and complications, for starters. Professor Wei Shen Lim, chairman of the Committee on Vaccination and Immunization, said at a briefing in Downing Street that there will be a list of priorities for those most at risk of dying from the disease.
Medical staff, the elderly and their carers are in the first place, followed by people in age groups up to over 60 years. Adults over 50 with health conditions would then be prioritized during the first phase of the program.
But when the vaccine is released, will you need it if you already have a coronavirus?
The Guardian reports that so far, vaccine experiments have focused on people who have not been exposed to the coronavirus, which means that the effect of the vaccine on people who have been exposed to it is unclear.
However, since studies suggest that immunity to Covid may last only a few months, experts suggest vaccination even if you have had it, because you can be re-infected.
Professor Robin Shattock of Imperial College London told the Guardian: “The level of immunity to natural infections is really variable, so some people get a very strong immune response and some people have a fairly weak immunity. The vaccine will complement the immune response and hopefully give you more protection. “
