COVID-19 vaccines are effective at protecting against severe forms of the disease. Research shows that the placentas of pregnant individuals are unharmed by the vaccines. By contrast, SARS-CoV-2 infection during pregnancy poses a higher risk of placental lesions and deficiencies, which places a pregnant individual at risk of complications.
COVID-19 are effective at preventing deaths and severe forms of the disease. The mass vaccination campaigns occurring worldwide have sped up the reopening of the economy. The workforce suffered from absence and working hours loss in 2022 due to the aftermath of the pandemic including long COVID.
Vaccination harnesses the capabilities of both the innate and adaptive arms of the immune system. Clinical trials and post-marketing studies showed that COVID-19 vaccines are safe for children. Although COVID-19 mRNA vaccines are associated with rare cases of myocarditis, post-vaccine myocarditis has a much better prognosis compared to COVID-19-associated myocarditis. The risk of myocarditis and future cardiovascular complications are higher with COVID-19. Therefore, COVID-19 vaccines’ benefits outweigh their possible risks even for children.
Available data show COVID-19 vaccines are safe and effective at preventing severe forms of the disease and death. Large clinical trials and post-marketing authorizations have shown that the vaccines’ benefits largely outweigh their possible risks.
COVID-19 bivalent vaccines are designed to provide protection against both the original SARS-CoV-2 and the Omicron variant. Safety signals from pharmacosurveillance systems aren’t enough to determine whether an actual risk exists. This requires additional investigation and comparison with other monitoring tools. The higher risk of stroke following vaccination detected in the VSD surveillance system hasn’t been confirmed in other systems nor in clinical studies.
Data from vaccine safety monitoring programs indicate that COVID-19 vaccines are safe and not associated with any increase in mortality or sudden deaths. While certain COVID-19 vaccines have been associated with a slightly increased risk of blood clotting and heart inflammation, these conditions are more likely to result from COVID-19 itself than from vaccination.
Numerous studies support the safety of hepatitis B and HPV vaccines. These vaccines prevent potentially life-threatening diseases, such as liver cancer due to chronic hepatitis B and cervical cancer due to the human papillomavirus. Vitamin K injections are routinely given to newborns in order to prevent dangerous bleeding due to vitamin K deficiency. These shots are safe and the presence of preservative substances is not a cause for concern.
Hydroxychloroquine and chloroquine are chiefly known for their ability to treat malaria, a parasitic infection. They are also used to treat other conditions, such as the autoimmune disease rheumatoid arthritis. However, clinical trials involving thousands of COVID-19 patients to date found that hydroxychloroquine doesn’t improve disease severity or mortality rate in COVID-19 patients. Health authorities recommend against using hydroxychloroquine to treat COVID-19.
Manufacturers and healthcare providers must report all serious adverse events that occur after COVID-19 vaccination, regardless of whether they think the vaccine was the cause. This is mandatory under the Emergency Use Authorization that the FDA issued for the COVID-19 vaccines. In 2021 and 2022, clinicians administered over 600 million vaccines, an unprecedented number under such authorization, leading to a spike in deaths reported to VAERS. Taken together, this indicates that the spike is due to an increased reporting rate and not a genuine increase in deaths.
Myocarditis is an inflammation of the heart muscle, which can be caused by viral infections, such as COVID-19 and the flu. The COVID-19 mRNA vaccines have also been associated with a higher risk of myocarditis, particularly in young men. However, the risk of myocarditis is significantly higher after COVID-19 than after vaccination. Reliable scientific evidence shows that the benefits of COVID-19 vaccination outweigh their risks.
