The COVID-19 vaccines authorized for emergency use by the U.S. Food and Drug Administration demonstrated a high level of safety and efficacy in protecting people from disease. Their ability to reduce transmission is unclear, but studies are underway. Due to the concern that vaccinated people may still transmit the virus to unvaccinated people, the former still need to practice preventative measures like mask-wearing and physical distancing. Unvaccinated people remain the majority of the population in most countries, since not everyone can be vaccinated at the same time due to issues like vaccine supply scarcity and labor shortages.

COVID-19 vaccines authorized for emergency use by the U.S. Food and Drug Administration demonstrated a high level of safety and efficacy in clinical trials. However, limited data is available regarding the safety and efficacy of these vaccines in pregnant women because they were excluded from initial clinical trials. Available evidence from animal studies and ongoing vaccine safety monitoring suggests that COVID-19 vaccines don’t pose any specific risk for pregnant women. In contrast, pregnant women have an increased risk of suffering complications from COVID-19, which may affect pregnancy outcomes.
COVID-19 vaccines authorized for emergency use by the U.S. Food and Drug Administration showed a high level of safety and efficacy in clinical trials. However, these trials excluded pregnant women. For this reason, data from clinical trials regarding the vaccines’ safety and efficacy in pregnant women is limited. However, current safety monitoring of pregnant women who received the vaccine hasn’t shown an increased incidence of pregnancy-related adverse events compared to unvaccinated pregnant women. The U.S. Centers for Disease Control and Prevention stated that “People who are pregnant and part of a group recommended to receive COVID-19 vaccine, such as healthcare personnel, may choose to be vaccinated”.
No vaccine can receive Emergency Use Authorization from the U.S. Food and Drug Administration (FDA) unless clinical trials demonstrate that it is safe and can prevent the disease in vaccinated individuals. Data from Phase 3 trials and continued monitoring of vaccinated individuals show that the COVID-19 vaccines approved by the FDA have a high level of efficacy and are generally safe. This evidence indicates that the benefits of the COVID-19 vaccines in preventing the disease largely outweigh potential risks, such as allergic reactions in a small number of people who have previous histories of allergies.
The COVID-19 vaccines approved for emergency use by the U.S. Food and Drug Administration were thoroughly reviewed for safety and efficacy before approval. Like any medicine or medical procedure, vaccines can also cause side effects in some vaccinated individuals. Some of the common side effects of the COVID-19 vaccines are pain at the injection site, fever, headache, and fatigue. However, these side effects are mild and short-lived compared to the risks associated with natural infection, such as long-term effects of COVID-19 and death.
Vaccines are considered one of the greatest medical achievements. They have eradicated smallpox and reduced global child mortality and long-lasting disabilities from vaccine-preventable diseases. Besides being effective in preventing the spread of contagious diseases, overwhelming evidence demonstrates that vaccines are also safe and do not increase the risk of developmental, neurological, or autoimmune conditions. Vaccines undergo extensive testing for safety and efficacy before license and are continuously monitored even after approval to identify any safety issue. Therefore, the proven benefits of vaccination far outweigh the potential risks.
Cloth face masks are safe for children over the age of two years old to wear, according to the American Academy of Pediatrics. To reduce the spread of COVID-19, it is important for children to practice the same precautionary measures as adults, such as mask-wearing, frequent handwashing, and physical distancing, to limit the spread of COVID-19. While children are generally less likely to develop severe COVID-19 symptoms, some develop serious illnesses following mild cases of COVID-19, which is known as multisystem inflammatory syndrome. Furthermore, children can still transmit the virus to populations that are at risk for severe COVID-19, like the elderly, albeit with a lower probability than adults.
Fainting, also known as syncope, can occur after vaccination. It is usually harmless in itself, although it can lead to injuries if the affected person falls, which can happen if they are not sitting or lying down at the moment of fainting. Episodes of vasovagal syncope are often triggered by pain and/or anxiety, which can lead to changes in heart rate and blood flow, resulting in a temporary loss of consciousness. The sight of blood or a needle can also trigger vasovagal syncope. Fainting following vaccination is not necessarily indicative of problems with the vaccine itself.
Multiple studies have established that vaccines are safe and not associated with increased rates of autism, cancer, or infertility. The National Childhood Vaccine Injury Act does not prevent people from suing a vaccine manufacturer for vaccine injuries. The U.S. Department of Health Resources and Services Administration explains that “Although the Act provides liability protections to vaccine manufacturers and vaccine administrators who administer covered vaccines in many circumstances, these protections are not absolute.” For instance, the Act does not provide manufacturers protection “when an individual files a petition and is requesting damages of $1,000 or less.” These protections also don’t hold if a vaccine manufacturer has been shown to be negligent.
Large-scale, reputable studies did not find a greater incidence of adverse health outcomes in vaccinated children compared to unvaccinated children. The authors of the study cited as the basis for this claim created a new metric that was not validated as a reliable proxy indicator to compare the incidence of illness in vaccinated and unvaccinated children. Due to this, the conclusions of the study are questionable.
