In the US four companies are known to be working on the Covid-19 vaccine and are on their final stage: Moderna, Pfizer, AstraZeneca, and Johnson & Johnson. Two companies out of these four – AstraZeneca and Johnson & Johnson have stopped their trial after the human testing phase 3 because many volunteers fell sick. The rest two vaccines also showed a few side effects. Even though the vaccines showed a few side effects, there was no adverse effect on the volunteers. The side effects lasted just a few days and were very mild, depending on the participant. It is can be said that these vaccines might also make it past the FDA as long as their side effects are not harsh or permanent.

The British company reported the first case of transverse myelitis on September 11, 2020. After reporting the first case of the side effect, the British company claimed that there was insufficient evidence to say for certain that the illnesses were or were not related to the vaccine. The company has now recommenced the trials in the U.K., Brazil, South Africa, and India. The company is yet to restart its phase 3 trial in the US. Also, read Countries That are COVID-19 Free

Johnson & Johnson: Side Effects

Johnson & Johnson gave vaccines to 60,000 volunteers. Among those 60,000 volunteers, one reported an explained illness during the trials. This illness became the reason for the pause of the Johnson & Johnson vaccine trial. The illness was not disclosed by the company or the participant due to their privacy agreements. Side effects from the vaccine trials don’t mean that they can not be successful in the future. With the uprising of the number of Covid-19 patients across the world, a successful vaccine is anxiously awaited. A vaccine with few side effects that are mild and temporary might get past the FDA approvals.
