The UK Health Security Agency (UKHSA) has called on citizens to get vaccinated against seasonal viral diseases as soon as possible ahead of Diwali celebrations. According to the agency's specialists, timely vaccination will help reduce the risk of illness during the holiday gatherings, when people actively interact with relatives and friends. UKHSA emphasizes that vaccination not only protects the individual but also reduces the likelihood of transmitting viruses to those around them — elderly relatives, children, and other vulnerable groups. The agency reminds that the winter season is traditionally accompanied by an increase in influenza and other respiratory infections, and the mass family and community gatherings characteristic of Diwali can contribute to faster virus spread. In this regard, specialists recommend that those who are eligible for free vaccination should not delay their visit to a doctor and book an appointment in advance so that immunity has time to develop before the start of the holiday. This is especially relevant for people in at-risk groups — the elderly, those with chronic diseases, and those with weakened immune systems. UKHSA views prevention as an important element of care not only for personal health but for community health as a whole, noting that collective vaccination helps contain the spread of seasonal infections across the entire country.
