Hepatitis B vaccines have been in childhood shots for decades. The new vaccine is for adults.

The hepatitis virus can damage the liver and is spread through contact with blood or other bodily fluids. Cases have been rising, a trend linked to the heroin and opioid epidemic. Meanwhile, researchers found older vaccines falter in diabetics and older adults.

The new vaccine uses an additive that boosts the body’s immune response. It is two shots given over one month.

The Advisory Committee on Immunization Practices endorsed the vaccine Wednesday in Atlanta. The government usually adopts its recommendations. VOA

    I was about to take Cruise Ship Management in school last year. But unfortunately, when I received the result in hepatitis b test, it was positive. I don’t know where I got this. I’ve never experienced having sex with any man or boyfriend. I was so disappointed at that time. But then again, it is never the end of the world. I repeated the test in a well-known hospital. But, it came back positive again. Early this year i purchase Hepatitis B herbal remedy online from BEST HEALTH HERBAL CENTRE. They told me i will be negative after 4-5 weeks of usage of their Hepatitis B herbal remedy, which i believed and have faith. After 5 weeks of usage, I did another test my HBsAg came negative in routine checkup, so I have done all investigations for hepatitis B. My test reports are HBsAg negative 0.04 on 22/02/2018. I will never stop telling the world about BEST HEALTH HERBAL CENTRE good work in human life …visit their web-page ww w .besthealthherbalcentre. com for more details.

U.S. Measles Outbreak Raises Concerns About Immunity in Adults

This has occurred even in adults with two documented doses of the vaccine, said Dr. Michael Phillips, chief epidemiologist at NYU Langone Health, which serves parts of New York City, a hot spot in the U.S. outbreak.

Adults in the United States who were vaccinated against measles decades ago may need a new dose depending on when they received the shot and their exposure risk, according to public health experts battling the nation’s largest outbreak since the virus was deemed eliminated in 2000.

Up to 10 percent of the 695 confirmed measles cases in the current outbreak occurred in people who received one or two doses of the vaccine, according to the U.S. Centers for Disease Control and Prevention.

The figure illustrates what can happen when a large number of individuals, even those who have been vaccinated, are exposed to the measles. CDC recommends that people who are living in or traveling to outbreak areas should check their vaccination status and consider getting a new dose.

Dr. Allison Bartlett, an infectious disease expert at the University of Chicago Medicine, said the “continued vulnerability to infection” is why high-risk adults such as healthcare workers are routinely advised to get a second dose of the measles vaccine if they have not had one.

But knowing your vaccination status can be tricky, experts said.

“It’s complicated and often futile because it’s very difficult to resurrect those old records,” said Dr. William Schaffner, an infectious disease expert at Vanderbilt University Medical Center.

People vaccinated in the United States since 1989 would most likely have received two doses of the combined measles, mumps and rubella (MMR) shot under federal guidelines, and that is still considered the standard for protection.

Anyone vaccinated between 1963 and 1989 would likely have received only one dose, with many people immunized in the earlier years receiving an inactivated version of the virus. Americans born before 1957 are considered immune as they would have been exposed to the virus directly in an outbreak.

Merck & Co Inc is the sole U.S. provider of the MMR vaccine. The company said in a statement that it has “taken steps to increase U.S. supply” of the vaccine due to the current outbreak.

HIGHLY CONTAGIOUS

The measles virus is highly contagious and can cause blindness, deafness, brain damage or death. It is currently spreading in outbreaks in many parts of the world.

According to the World Health Organization, 95 percent of a population needs to be vaccinated to provide “herd immunity,” a form of indirect protection that prevents infection in people too young or sick to be vaccinated. U.S. public health officials have blamed the current outbreak in part on rising rates of vaccine skepticism that have reduced measles immunity in certain communities.

For travelers to outbreak areas abroad, the CDC recommends adults consider getting another dose of MMR unless they have proof of receiving two prior doses, take a blood test showing immunity, or were born before 1957.

In general, the CDC says two doses of the measles vaccine should provide 97 percent protection; one dose should offer 93 percent protection. However, immunity can wane over time.

This has occurred even in adults with two documented doses of the vaccine, said Dr. Michael Phillips, chief epidemiologist at NYU Langone Health, which serves parts of New York City, a hot spot in the U.S. outbreak.

He said in kids, “the vaccine is really effective,” but in some adults, memory T-cells, which recognize and attack germs, do not fight the virus as effectively as they once did.

Adults who have any doubt about their immunity should get another dose, Schaffner said: “It’s safe. There’s no downside risk. Just roll up your sleeve.” (VOA)
