COVID-19 vaccines have some mild side effects, but they are they are extremely safe.
The Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) keep a close eye on the side effects of COVID-19 vaccines to ensure their safety, and all reactions are monitored and recorded.
Some people do not experience any side effects from COVID-19 vaccines, but when they occur, these typically include fever, headache, fatigue, muscle pain, diarrhoea, chills, and pain at the injection site. These are to be expected, and usually pass within 24 to 48 hours.
Efficacy rates of COVID-19 vaccines range from 80 to 95 percent. Most vaccines being administered worldwide are approved for emergency use by World Health Organization (WHO) or other respective national bodies. Post-vaccination COVID-19 infections and deaths are rare and often due to specific underlying health conditions.
The Lancet published a study that discussed vaccine side effects. Between December 8, 2020, and March 10, 2021, a survey-based study on the COVID-19 vaccine side effects gathered data on the vaccination's adverse effects among healthcare workers. The vaccine's effectiveness in lowering COVID-19 infection, severe disease, hospitalization, and death were observed. A reanalysis of the data indicated that the vaccines are 90 percent effective two weeks after the first dose.
On the other hand, COVID-19 is extremely dangerous and can make people seriously unwell, and can be lethal among even some healthy adults. Those who have contracted COVID-19 can also experience a range of long term, ongoing health issues, known as long COVID, which is are still not fully understood. The CDC notes that COVID-19 vaccines cannot make you sick with the virus, as they do not contain the virus itself.
So, while COVID-19 can make an individual seriously unwell, COVID-19 vaccines are not harmful, and are the best way to ensure yours and others safety.
