Whenever you get vaccinated for the coronavirus, there is a good chance you will need to get two doses of the vaccine. Two types of vaccines are expected to begin being distributed this month and both require two doses 28 days apart.Dr. Anthony Fauci said during a CNN town hall on Friday that the first vaccine is the “prime” vaccine dose, and the second one is a booster. The two vaccines, one from Pfizer and the other Moderna, are expected to receive an FDA emergency use authorization in the coming weeks.Fauci said another vaccine, one produced by Johnson and Johnson, would only require one shot. But Fauci cautioned that the data from that vaccine candidate has not been reviewed. The Moderna and Pfizer vaccines are showing an efficacy of 95%, and both vaccines had a near 100% effectiveness against severe coronavirus cases.While the first shot will offer some protection against the virus, Fauci says that the boost will give Americans “optimal” protection against the virus.“What you have is you get some degree, not optimal, but some degree of immunity a couple of weeks after the first dose,” Fauci said. “That's not optimal. After the second dose, you get optimal immunity anywhere from seven to 10 days after the second dose."As vaccine doses begin to make their way to health care workers and high risk patients, Fauci says it will be important for everyone, even those who are vaccinated, to still wear masks and conduct social distancing. Fauci says that those who are vaccinated could potentially carry the virus, even if they will not become symptomatic.Fauci said that it will take a vast majority of Americans getting vaccinated before the US reaches herd immunity. When the US reaches herd immunity, that is when social distancing measures can be eased, Fauci says. "Even if you're vaccinated, you may be protected against getting sick, but you may not necessarily be protected against getting infections. So you may have some virus in your nasal pharynx. It wouldn't bother you, and maybe it wouldn't even infect anybody else, but it would be there. That's the reason why you can't abandon all public health measures." 2151

WEST PALM BEACH, Fla. — If you were planning a vacation to the Bahamas this summer, you may need to rethink your plans.The island nation just announced sweeping restrictions for tourists, specifically from the United States. It’s an effort to curb the spread of COVID-19. The restrictions begin Wednesday, July 22.This comes after just reopening its borders to visitors earlier this month.In the prime minister's national address, he said the country has 15 new coronavirus cases for a total of 153. 507

With news of two highly effective COVID-19 vaccines on the horizon, health officials and scientists are giving us new insight into how we could gain herd immunity."If we think of the population as a single group of people with all similar risks and susceptibilities and behaviors, we need 60% of people to be immune, meaning that not only they don’t get sick, but also they don't pass on the virus to other people," says Dr. Stuart Ray, an infectious disease professor and herd immunity expert at Johns Hopkins University.Dr. Ray says achieving herd immunity with the help of a COVID-19 vaccine would mean enough people would either get the vaccine or already have recovered from the virus and be immune to help stop the spread of the virus."It's a little bit like this notion that if you’re going to pass on a message from a lot of people in a group, they have to speak the same language. And the more people don't speak the language, the harder it's going to be to pass that message and there’s a threshold at which the message just gets stopped," says Dr. Ray.Still, it would take a certain number of people to get the vaccine and have that immunity last in order to reach herd immunity. Stanford University's Dr. Bali Pulendran hopes that we can achieve herd immunity, even though there are a certain number of people who are still hesitant to take the vaccine."I think we should remember that a vaccine that is 95% effective is only effective if the majority of people in a population take it. If only half the population or only 60% of the population take it, then we are unlikely to have achieved the level of herd immunity that you need for curbing the disease," says Dr. Pulendran.And if the new COVID-19 vaccine requires two doses, how crucial will it be to make sure people receive that second round of immunization?Asked whether follow up will be a concern, Dr. Ray says, "I think it is a possible concern. We’re going to do a lot of learning. So, one of the things we’ve learned is that some vaccines we thought you needed multiple doses, one dose works pretty well."Doctors say research will be ongoing on the vaccine and the virus itself to ensure people will be protected as much as possible, because so many are hopeful for an end to COVID-19. 2268

When Francesca Marie McNally was born, she was the perfect baby. “Perfectly healthy. Beautiful. Very interactive,” describes her dad, Sean McNally. He and his wife Veronica were in love with their little girl. Just before she turned three months old, she started coughing.  “We saw four doctors,” said Veronica. “None of the doctors we were seeing, and there were so many, really knew what it was,” said Sean.After not getting answers from their pediatrician's office and local emergency rooms, they took their baby to Children’s Hospital of Michigan in Detroit. Doctors there immediately recognized how serious the situation was. She was rushed into intensive care. She did not make it. “It is with me every day. I think about her every day. I feel that loss every day,” said Veronica. Doctors found out too late that Francesca had whooping cough and they also found out how she caught it. “I had whooping cough. I don’t know where I got it from. I look back and wish that I would have known more about the way I could have protected myself and my family,” said Veronica. Babies cannot be vaccinated against whooping cough, but doctors recommend those who care for them are. Veronica says she asked why she wasn’t told this during her pregnancy. According to medical records, on the day of her delivery, a nurse offered her the Tdap shot, which is the whooping cough vaccine. 1449

When United Flight 93 crashed in Shanksville, PA, on Sept. 11, 2001, John Gerula was one of the first on the scene as a volunteer firefighter. The experience inspired John, still in high school, to enlist in the Marines. He shipped out to Iraq two years later, and today he bears the invisible wounds of war.Over the course of 18 months in Fallujah and Operation Phantom Fury, Gerula survived 21 improvised explosive device blasts, resulting in a severe traumatic brain injury that gave him migraines and memory loss, and post-traumatic stress that left him anxious, isolated and abusing alcohol.“I would spend a lot of time by myself at home on my property, just away from people,” Gerula says. “I didn't like large crowds, just the things that brought me back to what caused my issues, the flashbacks and everything.”That all changed this summer when Oliver, Gerula’s service dog, came into his life.”He can sense when I start to breathe heavy, when my heart rate's high, things of that nature, he comes up to me allows me to pet him,” Gerula says. “Since I’ve had Oliver, I’ve not had a drop of alcohol. I gave up drinking altogether. So he has made huge changes in my life.”Gerula and Oliver are among the first four pairs of veterans and service dogs to graduate from American Humane’s “Shelter to Service” program, created to combat the staggering statistics of 20 veterans committing suicide daily due to PTSD and TBI, and the 670,000 dogs euthanized every year in America’s animal shelters.“We saw a great opportunity to uplift the healing power of the human-animal bond by taking incredible dogs who were abandoned, who needed a second chance at life, giving them unbelievable, rigorous training, and then matching them with our veterans, allowing these veterans a chance for healing, hope, compassion, and love,” says American Humane’s President and CEO Robin Ganzert.Ganzert’s organization is currently training its second “Shelter to Service” class while advocating for a bill on Capitol Hill to establish national training standards and speed up the service dog waitlist, which currently runs from 18 to 24 months.And Gerula has a message to veterans seeking the help with their own struggles.“Don't give up,” he says. “The best thing to do is to keep going and just go do every option you can.” 2346
