The deaths were unrelated adults from the Baltimore region with no underlying health problems. Officials confirmed that one of the deceased was Walter Brooks Jr., 18, who died Oct. 21. Maryland is among 46 states where the virus is widespread, contributing to 279 hospitalizations statewide. Around the country, more than 1,000 people have died of complications from swine flu and more than 20,000 have been hospitalized, according to the Centers for Disease Control and Prevention. As deaths and hospitalizations continue to rise, public health officers are struggling with a shortfall of H1N1 vaccine, resulting in a shortage for even groups most susceptible to the virus -- children, pregnant women and people with underlying health problems. State health officials have ordered 420,000 does of the swine flu vaccine and say more is on the way. Federal officials tried to assure the public Tuesday that vaccine supplies are increasing and there soon will be enough vaccine for everyone who wants it. Officials said 22 million doses of vaccine are now available, up from 14 million last week, which was much lower than initial predictions of 120 million doses by the end of October.
