**Coronavirus: The vaccines that could end the pandemic**.
Two vaccines against the coronavirus have been shown to be highly effective in preventing people from getting sick. The vaccines, developed by Pfizer and Moderna, both use messenger RNA (mRNA) technology to teach the body to make proteins that are part of the virus. This allows the immune system to recognize and attack the virus if it enters the body..
The Pfizer vaccine was shown to be 95% effective in preventing symptomatic COVID-19 in a clinical trial of more than 43,000 people. The Moderna vaccine was shown to be 94% effective in preventing symptomatic COVID-19 in a clinical trial of more than 30,000 people..
Both vaccines are given in two doses, spaced several weeks apart. The Pfizer vaccine is given 21 days apart, while the Moderna vaccine is given 28 days apart..
The vaccines are safe and well-tolerated. The most common side effects are pain at the injection site, fatigue, headache, and muscle aches. These side effects usually go away within a few days..
The vaccines are a major step forward in the fight against the coronavirus pandemic. They are safe and effective, and they could help to end the pandemic..
**How do the vaccines work?**.
The Pfizer and Moderna vaccines both use mRNA technology to teach the body to make proteins that are part of the virus. This allows the immune system to recognize and attack the virus if it enters the body..
mRNA is a molecule that carries instructions for making proteins. When the mRNA from the vaccine enters a cell, it is translated into a protein. This protein is then displayed on the surface of the cell. The immune system then recognizes the protein and attacks it..
This process helps the immune system to learn how to recognize and attack the virus if it enters the body. This can help to prevent people from getting sick from COVID-19..
**Are the vaccines safe?**.
The Pfizer and Moderna vaccines are safe and well-tolerated. The most common side effects are pain at the injection site, fatigue, headache, and muscle aches. These side effects usually go away within a few days..
The vaccines have been tested in clinical trials involving tens of thousands of people. The trials have shown that the vaccines are safe and effective..
**When will the vaccines be available?**.
The Pfizer and Moderna vaccines are expected to be available in the United States in December 2020. The vaccines will be distributed to healthcare workers and other high-risk groups first..
The vaccines will then be available to the general public in early 2021..
**What should I do if I get vaccinated?**.
If you get vaccinated, you should continue to follow public health guidelines, such as wearing a mask, social distancing, and washing your hands frequently. This will help to protect you and others from COVID-19..
The vaccines are a major step forward in the fight against the coronavirus pandemic. They are safe and effective, and they could help to end the pandemic..
