Should i take vaccines

Some recently immunised people have suffered unusual clots, including a type in the brain called cerebral sinus vein thrombosis CSVT. This is not proof that the vaccine is to blame. Covid infection itself can also make clots more likely and they can occur naturally too.

Experts stress the benefits of vaccination outweigh the risks for the vast majority of people, but is more finely balanced for younger adults. As a precaution, regulators are continuing to monitor the situation and advise symptoms, such as unusual bruising or persistent headache after vaccination , should prompt a medical check.

And adults under 40 in the UK will be offered a different Covid vaccine. Safety trials begin in the lab, with tests and research on cells and animals, before moving on to human studies. The principle is to start small and only move to the next stage of testing if there are no outstanding safety concerns.

If the safety data from the labs is good, scientists can check the vaccine or treatment is effective. That means tests on large numbers of volunteers - about 40, in the case of Pfizer-BioNTech, the first to be approved in the UK. Half are given the vaccine and the other half a placebo jab. The researchers and participants are not told which group is which, until after the results, to avoid bias. All of the work and findings are checked and verified independently.

The Covid vaccine trials happened at breakneck speed, but they didn't skip any steps - they were able to move faster because so many people were involved and other projects were put aside. Scientists hope to tweak coronavirus vaccines to ensure they continue to offer high protection as new variants of the disease emerge. The UK's drug regulator says new vaccines can be fast-tracked for approval if needed.

But lengthy clinical trials with thousands of volunteers will not be needed. Instead, data from existing studies and ongoing real-world use could be used. Vaccines do not give you a disease. Instead, they teach your body's immune system to recognise and fight the infection they have been designed to protect against. Some people do experience mild to moderate symptoms after being vaccinated. Certain individuals with a compromised immune system are typically advised to wait.

And people who have experienced allergic reactions to a particular vaccine are generally told to avoid follow-up doses. You should not get vaccinated for influenza if you:. Some people may not be able to receive the live influenza vaccine LAIV , which is the nasal spray flu vaccine.

Talk with your doctor if any of the following apply to you or your child:. You may have heard that people with egg allergies cannot receive a flu vaccine. That used to be true, but the CDC has changed its recommendation. If you get hives or other mild reactions from eating eggs, you can safely receive any flu vaccine. If you experience more severe reactions from eggs, such as swelling or trouble breathing, you can also get a flu vaccine.

However, it should be done under the supervision of a healthcare provider who can manage those symptoms. Hepatitis A HepA is a virus that causes liver disease. It also emphasizes the importance of receiving the vaccine for individuals traveling to high-risk areas. These areas include:. People who are sick are generally advised to wait for the vaccination.

Pregnant women may also be advised to wait for the vaccination. However, the risk to the fetus is low. If a pregnant woman is at high risk for HepA, vaccination may still be recommended.

Hepatitis B HepB is another virus that can cause liver disease. It can spread from infected blood or body fluids, as well as from a mother to her newborn child. People with chronic HepB infection are at increased risk of end-stage liver disease cirrhosis , as well as liver cancer. Routine vaccination is recommended.

However, certain people should not receive the HepB vaccine. Risk factors include:. Most HPV infections go away without the need for treatment. It can also help prevent other HPV-related diseases including:.

The Tdap vaccine protects against tetanus , diphtheria , and pertussis. The Td vaccine protects against tetanus and diphtheria. Widespread vaccination has greatly decreased the serious consequences of these diseases. Routine vaccines are recommended. Vaccines will help keep you healthy The Centers for Disease Control and Prevention CDC recommends vaccinations throughout your life to protect against many infections. When you skip vaccines, you leave yourself vulnerable to illnesses such as shingles, pneumococcal disease, flu, and HPV and hepatitis B, both leading causes of cancer.

Vaccines are as important to your overall health as diet and exercise Like eating healthy foods, exercising, and getting regular check-ups, vaccines play a vital role in keeping you healthy. Vaccines are one of the most convenient and safest preventive care measures available. Vaccination can mean the difference between life and death Vaccine-preventable infections can be deadly.

Vaccines are safe The US has a robust approval process to ensure that all licensed vaccines are safe.
