No vaccine is 100% effective. For example the measles vaccine has saved many lives but is not 100% effective. And because of widespread vaccination in the US measles is very rare ... however those who travel to largely unvaccinated parts of the world can bring it back to the US.
Here is what the CDC says about the measles vaccine.
Measles Vaccination
Pronounced (MEE-zills)
"Measles is a very contagious disease caused by a virus. It spreads through the air when an infected person coughs or sneezes. Measles starts with a cough, runny nose, red eyes, and fever. Then a rash of tiny, red spots breaks out. It starts at the head and spreads to the rest of the body.
Measles can be prevented with MMR vaccine. The vaccine protects against three diseases: measles, mumps, and rubella. CDC recommends children get two doses of MMR vaccine, starting with the first dose at 12 through 15 months of age, and the second dose at 4 through 6 years of age. Teens and adults should also be up to date on their MMR vaccination.
The MMR vaccine is very safe and effective. Two doses of MMR vaccine are about 97% effective at preventing measles; one dose is about 93% effective.
Children may also get MMRV vaccine, which protects against measles, mumps, rubella, and varicella (chickenpox). This vaccine is only licensed for use in children who are 12 months through 12 years of age.
Before the measles vaccination program started in 1963, an estimated 3 to 4 million people got measles each year in the United States. Of these, approximately 500,000 cases were reported each year to CDC; of these, 400 to 500 died, 48,000 were hospitalized, and 1,000 developed encephalitis (brain swelling) from measles. Since then, widespread use of measles virus-containing vaccine has led to a greater than 99% reduction in measles cases compared with the pre-vaccine era. However, measles is still common in other countries. Unvaccinated people continue to get measles while abroad and bring the disease into the United States and spread it to others."
As I have travelled around the world many times I have received many vaccinations for many deadly diseases...and I have received the Covid vaccine 3 times! I recommend it. And I also recommend the highly effective, but imperfect Shingles vaccine! We are very blessed to have these available!
I am very glad to see Sorrento help develop more effective Covid vaccines which are are also cheaper and more accessible to the third world nations. Those along with Sorrento's many therapies can save many lives!
