And, in countries like China and Russia, there are even some that have already been approved for limited use.
Precisely when an approved vaccine will be widely available in the U. Or, is it that they are different, and that, in reality, a vaccine is more effective? The hope is, these antibodies provide immunity to that infection and prevent you from contracting it.
A cure, on the other hand, treats diseases or infections differently than a vaccine by attacking an illness after a person has already contracted it.

That includes developing vaccines to prevent the disease, as well as testing out new or repurposed medications in the hopes that they might help patients severely ill with COVID, the disease caused by the novel coronavirus, recover. Vaccines prepare the body's immune system to fight off a disease, ideally preventing people from falling ill.
Treatments are typically used when patients are already sick with a certain disease, or sometimes as a way to prevent the onset of an illness.

Even after a drug or vaccine has been given full approval, the FDA might continue to monitor it for unexpected side effects or for more information that might be helpful to know. For example, it is not yet clear how likely it is that someone who gets one of the vaccines could still spread the virus to others.
This is still being studied, as are any possible long-term effects of the vaccines. Researchers are also still trying to determine how long the vaccines will provide protection against the virus. For the vaccines that require two shots as part of the initial series, the side effects might be a little stronger after the second shot compared to what you might have had after the first injection. In general, the side effects tend to go away within a few days. Some people might have swelling or tenderness of the lymph nodes under the arm in which they got the injection.
A swollen lymph node under the arm might cause concern, since this can also be a sign of breast cancer as well as some other cancers - see below. The time it takes for the lymph nodes to shrink back down after the vaccine may be a few days to a few weeks, although this is still being studied. If you notice swollen or tender lymph nodes that do not go away after a few weeks or if they continue to get bigger , contact your doctor to discuss the next steps.
For those with any type of cancer or a history of cancer: Many types of cancer can spread to nearby lymph nodes and some types of cancer can start in the lymph nodes. This can cause the nodes to become enlarged. In very rare cases, people have had serious allergic reactions after getting one of the vaccines. This seems to be more likely in people who have had serious allergic reactions before. Platelets are cells that normally help in blood clotting. Most of these events have happened in women between the ages of 18 and 59, and from 6 to 15 days after getting the vaccine.
People getting the vaccine and their caregivers should review the Janssen Fact Sheet for Recipients and Caregivers to learn more about the possible benefits and risks of the vaccine. You should also contact your health care provider if you have symptoms that might be from a low platelet count, such as new or easy bruising, or tiny purple or red spots on the skin that might look like a rash. A small proportion of people who have received the Pfizer-BioNTech and Moderna vaccines have developed myocarditis inflammation of the heart muscle or pericarditis inflammation of the lining outside of the heart.
In most cases, the symptoms started a few days after the second vaccine dose and were more likely to happen in adolescents and young adults. For people who received the Pfizer-BioNTech vaccine , the risk was highest in boys 12 to 17 years of age and then in men under the age of If you receive either the Pfizer-BioNTech or Moderna vaccine and start to have chest pain, shortness of breath, or feelings of having a fast-beating, fluttering, or pounding heart, the FDA and CDC recommend getting medical attention right away.
People getting these vaccines and their caregivers should review the Moderna Fact Sheet for Recipients and Caregivers and the Pfizer-BioNTech Fact Sheet for Recipients and Caregivers to learn more about the possible benefits and risks of these two vaccines. This can lead to muscle weakness and other symptoms.
The FDA advises you to get medical attention right away if you develop any of these symptoms after getting the Janssen vaccine. People getting this vaccine and their caregivers should review the Janssen Fact Sheet for Recipients and Caregivers to learn more about the possible benefits and risks of the vaccine.
Some cancer treatments like chemotherapy chemo , radiation , stem cell or bone marrow transplant , or immunotherapy can affect the immune system, which might make the vaccine less effective. People with certain types of cancers, like leukemias or lymphomas , can also have weakened immune systems which might make the vaccine less effective.
