There’s a lot of scare-mongering out there, but don’t believe everything you hear
Myth 1: The Covid-19 vaccine will affect a woman’s fertility
This myth was sparked when a social media post was shared in December 2020 by Dr Wolfgang Wodarg, a physician and former chief scientist for allergy and respiratory therapy at Pfizer, and Dr Michael Yeadon, a pulmonologist. They claimed that the spike protein on the coronavirus was the same as the spike protein that is responsible for the growth and attachment of the placenta during pregnancy. The fear was that, as a result of the vaccine, the immune system would not be able to differentiate between the two spike proteins and would attack the placental protein.
This is untrue. The overall makeup of the placental protein is very different from the coronavirus spike protein. Additionally, during the Pfizer vaccine tests, 23 women volunteers became pregnant after taking the vaccine.
Furthermore, the benefits of being vaccinated outweigh the risks of infection for pregnant women.
Myth 2: I’ve had Covid-19, so I don’t need a vaccine
Reinfection with SARS-CoV-2, the virus that causes Covid-19, can occur even in individuals who have previously contracted the virus. But receiving the vaccine can provide protection against severe Covid-19 complications.
The level of protection that is achieved from natural immunity after being infected by the virus is unknown. But scientists believe that the vaccine provides better protection than natural infection.
Myth 3: Covid-19 vaccine side-effects are dangerous
Most of the side effects of the Covid-19 vaccine are mild. They include low grade fever, sore arm and fatigue, and these usually subside after one to three days.
Rare side effects such as blood clots have been reported from the Johnson and Johnson vaccine. The chances of experiencing this side effect are low. The risks of blood clots as a result of Covid-19 infection are eight-10 times higher than risks associated with the vaccine. Doctors are aware of this concern and are trained to identify and treat the condition quickly.
A recent article by Healthline — a medically reviewed and fact checked website — compared the benefits and risks of being vaccinated with those of contracting Covid-19. Lung damage is a complication of Covid-19 while muscle fatigue can be a side effect of the vaccine. This risk-benefit decision is left to the individual to make, but vaccinations have been proven to be safe.
Myth 4: Vaccines have a microchip that will track and control an individual
This conspiracy theory has been propagated by anti-vaxxers who believe that the American business magnate, investor, and philanthropist Bill Gates will implant microchips to track people’s movement, using the vaccine as the method of delivery. This is untrue and has been clarified by Gates in the media.
This myth gained traction when a video was shared on Facebook making false claims about the optional microchip on the syringe’s label of the Covid-19 vaccine. This microchip’s purpose is to confirm that the injectable and the vaccine are not counterfeit and haven’t expired. It will also confirm if the injection has been used.
People commenting on the video appeared to have misinterpreted the technology as an injectable. But the microchip is part of the syringe label and not the injectable substance itself.
Myth 5: The Covid-19 vaccine development was rushed, so it may not be effective
The vaccine was developed very quickly. This was possible because the vaccine technology had been in development for many years. When the genetic information of SARS-CoV-2 was identified, the process could begin quickly. There were sufficient resources to fund the research and social media made it easier to recruit participants for the clinical trials. Because SARS-CoV-2 is contagious, it was easy to tell whether the vaccine worked or not.
Myth 6: The Covid-19 vaccine can alter my DNA
The messenger RNA vaccine (Pfizer) and the viral vector vaccine (Johnson and Johnson) cause your body to develop protection, so that when you are infected by SARS-CoV-2, your body is prepared to fight the virus. DNA is located in the nucleus of your cells and the vaccine material does not enter the nucleus. So it does not alter the DNA.
Social media plays a huge role in propagating myths and conspiracy theories. Before you share any information, you should ensure that it is from a scientific and reputable source.
