There are online credible sources that you can use to verify information. These include but are not limited to WHO's Vaccine Safety Net, The Immunization Action Coalition, The National Network for Immunization Information and The University of California San Francisco's Evaluation Health Information.
On the other hand, there is a huge increase in online threats. Most posts are harmless but, 5,000 websites and 20,000 social media posts were suspicious. If money is asked for, these are fake and can contain malware which can infect your computer or steal information from you.
A COVID -19 vaccine will not make you magnetic. They do not contain ingredients that can produce an electromagnetic field at the injection site. All are free from metals such as iron, nickel, cobalt, lithium and rare earth alloys as well as any manufactured products such as microelectronics, electrodes, carbon nanotubes and nanowire semiconductors. Furthermore, the typical dose is less than a milliliter (1/30th of an ounce), which is not enough to allow magnets to be attracted to a vaccination site even if the vaccines were filled with a magnetic metal.
There is not any release of any of the vaccine components in or outside the body. Vaccine shedding can only occur when a vaccine contains a weakened version of the virus. None of the vaccines used in the U.S. contain a live virus. It is not possible for any of the vaccine components to accumulate in the body's tissue or organs, including the ovaries. There is no evidence that vaccination causes any problems with pregnancy, including the development of the placenta. There is no evidence that fertility problems are a side effect of any vaccine.
They do not change or interact with DNA in any way. The material never enters the nucleus of the cell , which is where DNA is located. All COVID-19 vaccines work with the body's natural defenses to safely develop immunity to disease. Multiple Millions in the U. S. have received the vaccine. They have undergone and will continue to have the most intensive safety monitoring system in U.S history.
Some have no side effects. Others have had common side effects like swelling, redness and pain at the injections site, fever, headache, tiredness, and/or muscle pain. Serious safety problems are rare. To date, there have been two types of health problems after vaccination, both of which are rare. One is a severe allergic reaction. Providers have medicines to effectively and immediately treat the reaction which will occur within 15-30 minutes while one is being monitored. After the J & J vaccine blood clots with low platelets can occur. Platelets are present in blood to prevent bleeding. It occurs at a rate of 7 per million vaccinated women between 18 and 49 years old. For women 50 years and older the event is rarer. This major problem has not been seen with other COVID-19 vaccines.
There are cases of myocarditis (inflammation of the heart muscle) and pericarditis in teens and young adults. The benefits of COVID-19 vaccination outweigh these risks. Experts continue to recommend vaccination for anyone 12 years of age and older. There are variants of concern, for which there is evidence of an increase in spread, and perhaps more severe disease.
