More than 450,000 patients between 65 and 79 years old in Galicia will be “invited” by the Department of Health of the Xunta to participate in a study on the effectiveness of the reinforced flu vaccine in that age group after in previous years Its greatest benefits have been proven in people over 80. The research, the first of its kind on this formula in Spain, is carried out by the Group of Xenetics, Vaccines and Infectious Diseases (GENVIP) of the Health Research Institute of Santiago (IDIS). The trial, known as Galflu, is based on the hypothesis that this “double” or “high load” vaccine provides even greater protection “before reaching the age of 80,” explains Federico Martinón, promoter and principal investigator. The doctor presented the plans this Tuesday morning in the IDIS laboratories in Santiago, with the director of Public Health of the Xunta, Carmen Durán.
The entire population of Galicia between 65 and 79 years old who comes to get vaccinated against the flu in this annual campaign in large venues located in each health area will receive information about the clinical trial of this reinforced formulation and will be able to choose whether or not they want to receive it. inoculate The invitation to participate will be sent to patients via the SMS with which they normally make an appointment for vaccination against flu and covid-19. There is only one comparable test case known in Denmark, within the European Union, and no other of this size in Spain, Martinón said during the press conference.
There are different types of flu vaccines, and two different ones will be used in this season’s campaign: a high-dose one (Efluelda) and a standard one (Influvac Tetra). The difference is in the amount of antigens capable of generating protection in the body. The reinforced vaccine proved to be more effective in the prevention and complications of respiratory infection in people over 80 years of age, which is why it is routinely administered to this group. Now, it is also about checking whether the serum with more antigens reduces cases, hospitalizations and associated complications in somewhat younger people, between 65 and 79 years old, who until now were administered the standard one. The trial plans to vaccinate 50% of the participants with the reinforced formula and the other half of patients with the usual one to date.
The study does not imply subsequent clinical follow-ups, but rather the information needed will be obtained from your medical history until the following May. Only the research team will have access to this data, according to the Galician Health Service (Sergas). The general director of Public Health took advantage of the appearance to give the first data of the campaign: some 30,000 Galicians over 80 years of age participated on Monday of this week in the first day of double vaccination against flu and covid-19 in the health centers. To these we must add, Durán said, “between 24,000 and 26,000” people who already received these vaccines in residences and other social and health centers on previous dates.
There are, in total, around 58,500 patients vaccinated in Galicia against the flu and almost 55,000 against the coronavirus. The difference of 3,500, the head of Health explained, is due to people who had recently had Covid and “must wait three months to receive the dose.” Next week, starting on October 26, the so-called “vaccination centers” will reopen to immunize those under 80 years of age.
On the other side of life, Durán has spoken about vaccination against the respiratory syncytial virus (RSV), which so far has reached some 7,000 babies in Galicia. It is an immunization that Sergas has offered for newborns since last September 25 and that has accumulated an acceptance rate, by families, of 95%. At the same time, a “recapture” campaign is being deployed, aimed at babies born on or after April 1, and thus it has been possible to supply some 5,700 children, 80% of the total.
