A GROUP of doctors say natural immunity to coronavirus infection is long lasting but fear people will be coerced into taking top-up vaccines in order to re-access society when their Digital Green Pass expires after just six months.
By Oliver May
Doctors for Covid Ethics, a group of doctors across Europe and North America, say studies on Covid-19’s closest-related virus to infect humans, SARS, revealed that those who had acquired natural immunity in 2003 remain protected even now. They also maintain that, even before the onset of vaccination campaigns, most people had become immune to Covid-19, either through infection with the virus itself, often without symptoms or with only mild, uncharacteristic ones, or due to cross-immunity conferred by other, naturally occurring coronaviruses.
But under an Article of Law Decree just published by the European Union, its proposed Digital Green Pass will have validity for just six months. Once this expires the holder would need to be re-vaccinated or have had Covid in the last six months or take a test every 48 hours in order to regain their freedoms.
Doctors for Covid Ethics argue there is no rational case for such a pass, which is currently being used in Israel and proposed in the UK, adding that immunity from infection is likely to be durable and unaffected by variants.
Doctors for Covid Ethics said: “There is no scientific foundation to the concept of vaccine passports and no rational case at all for vaccine passports. To set a six-month cut-off is bizarre and arbitrary. Examining the time course of antibodies in blood samples is not a valid approach to the question of, ‘how long does immunity last?’.
“This is because antibodies aren’t the most important host defence mechanism in immunity to viruses. That’s considered to be T-cell memory (cytotoxic as well as ‘helper’ lymphocytes) and B-memory (antibody producing) cells. Antibodies naturally fall over time if you’re no longer constantly rechallenged with the infective pathogen. As community prevalence falls away, this re-exposure to the virus also diminishes.
