Vacuna covid - 10 things to know with detail
- 1. Effectiveness: The COVID-19 vaccines currently authorized for emergency use have been shown to be highly effective in preventing severe illness, hospitalization, and death from the virus.
- 2. Types of vaccines: There are several different types of COVID-19 vaccines, including mRNA vaccines (Pfizer-BioNTech and Moderna), viral vector vaccines (Johnson & Johnson and AstraZeneca), and protein subunit vaccines (Novavax).
- 3. Side effects: Common side effects of the COVID-19 vaccines include pain at the injection site, fatigue, headache, muscle aches, and fever. These side effects are usually mild and go away on their own within a few days.
- 4. Safety: The COVID-19 vaccines have undergone rigorous testing in clinical trials to ensure their safety. The vaccines are also continuously monitored for any potential side effects through post-marketing surveillance.
- 5. Age recommendations: The COVID-19 vaccines have different age recommendations depending on the specific vaccine. Some vaccines are authorized for use in individuals 16 and older, while others are authorized for individuals 18 and older.
- 6. Dosage: Most COVID-19 vaccines require two doses to achieve maximum protection. The timing between doses varies depending on the specific vaccine, but typically ranges from three to four weeks.
- 7. Storage requirements: Different COVID-19 vaccines have different storage requirements. For example, the Pfizer-BioNTech vaccine needs to be stored at ultra-cold temperatures, while the Johnson & Johnson vaccine can be stored at regular refrigerator temperatures.
- 8. Duration of protection: It is currently unknown how long immunity from the COVID-19 vaccines will last. Studies are ongoing to determine the duration of protection and whether booster doses will be needed in the future.
- 9. Vaccination prioritization: Due to limited vaccine supply, most countries have implemented vaccination prioritization plans to ensure that those at highest risk of severe illness are vaccinated first. These prioritization plans may vary by country and region.
- 10. Public health measures: Even after receiving the COVID-19 vaccine, it is important to continue following public health measures such as wearing masks, practicing social distancing, and washing hands frequently to help prevent the spread of the virus.
