Alabama is now the 23rd state to report a case of the measles, the highly contagious virus thought to have been all but wiped out in the USA since 2000. "You can't be over-vaccinated", he said.
The U.S.is experiencing the greatest spike in measles cases in 25 years, but Merck, the sole producer of the measles vaccine for the U.S., says it has production in hand.
Most of the measles cases during the recent historic outbreak have occurred in children, but adults in high risk environments - like UCLA or California State University, Los Angeles, where people were exposed to the virus - may need to get another dose of the vaccine, according to the the Centers for Disease Control and Prevention.
"You can certainly get one from your family doctor, but you can also go to your local pharmacy", said Weaver. "That means the majority of parents are making sure their children get vaccinated according to CDC's recommended immunization schedule", he noted.
Since 2012, all cases of measles in New Zealand have been linked to travellers bringing the disease from overseas, according to the Ministry of Health.
This is from Chief Medical Officer Dr Cheryl Peek-Ball who said, "Bermuda's public health sector is on a "guarded level" of alert due to the ongoing occurrences of measles in North America, the Caribbean and Europe".
Measles is so contagious that 90 percent of unvaccinated people who come in contact with an infected person will get the virus.
Measles is nearly entirely preventable through two doses of the MMR vaccine.
The best way to prevent a measles infection is vaccination.
Close to 100 cases of measles have been confirmed in New Zealand so far this year. After two doses, more than 99 per cent of people are protected. The CDC recommends two doses of MMR vaccine for children, the first at age 12 to 15 months and the second between 4 and 6 years. Adults who are at high-risk for exposure, including college students and worldwide travelers, are advised to get two doses. "So people who were vaccinated from 1963 to 1968 - that needs to happen".
People traveling internationally should receive their vaccines at least two weeks before departure, but even if their trip is less than two weeks away, they should still get a vaccine dose. Many Indiana adults may not be aware of their vaccination status or may have received a single dose of inactive virus, which does not provide the full protection. These individuals are encouraged to ask their healthcare provider about receiving a dose of MMR. Also, adults who had only one dose as a child who are attending college, work in the health care field or travel internationally are recommended to receive the booster shot, the CDC said.
