On-Demand Webinar – Vaccines

COVID-19 Vaccines and Health Care Workers

The pandemic of COVID-19 has been curbed in many countries due to the arrival of a number of efficacious vaccines. Yet, there are many unknowns in the evolving COVID-19 vaccine story, although we now see the emerging true situation in a better light, with reports of their efficacy ranging from 55% to 95 % depending on the vaccine strain. However, this situation is compounded by the reported vagaries of the increasing number of brand-name vaccines, manufactured on both the new and old vaccine platforms. These include their adverse effects, the emergence of possible vaccine-resistant viral variants (e.g. the current delta and lambda strains of SRAS-CoV-2), the efficacy of mixed mode vaccinations, necessity of booster doses and their immunological correlates, as well as reasons for vaccine resistance by a small proportion of the populace. This presentation will provide the details of the foregoing, as well as an outline of the basic mechanisms of vaccines, with a particular emphasis on those available in Sri Lanka.

World Oral Health Day 20th March 2020 – Be Proud Of Your Mouth

The World Dental Federation (FDI) unveiled the three-year theme (2021 – 2023) for its annual World Oral Health Day (WOHD) event, encouraging people across the globe to “Be Proud of Your Mouth”. By adopting this theme, FDI is hoping to “motivate people to value and take care of their mouths and understand that by doing so, they can also help protect their general health and well-being.”
World Oral Health Day was observed on March 20. This year, free dental check-ups, oral health counselling and preventive procedures was carried out at the community space adjacent to the Harbour Centre running along the Nubukalou Creek.
The Fiji Dental Association and the Fiji Dental Students Association partnering with the School of Dentistry and Oral Health, Fiji National University, Colgate Palmolive (Fiji) Limited, Wrigleys Oral Health Care Program and the Suva City Council to deliver this service.
Four key messages are being put forward as part of the “Be Proud of Your Mouth campaign:

  • Oral health is one of the main pillars of overall health and well-being
  • Managing risk factors for oral diseases can also help avoid other health conditions
  • Most oral health conditions are largely preventable and can be treated in their early stages
  • Universal Health Coverage: every person, everywhere should have access to the health services they need without the risk of financial hardship when paying for the services
