In your daily routine, pneumococci could always be transmitted via respiratory droplets or contact with articles soiled with respiratory discharges, particularly in the course of having meals. Pneumococcal infection could lead to consequences with different levels of severity, including sinus, middle ear infection, bacteremic pneumonia, sepsis, and meningitis. These diseases could be lethal. Among all the age groups, children and elderly are recommended to receive PCV13 (one dose) for better protection as their situations are often more critical.
Any individuals who have experienced Chickenpox could also face the threats of developing. Risks for Shingles grow with ages, stresses, lack of sleep and etc. Once the immune system is weakened, the virus that lie dormant could be reactivated. It is not easy to have a full recovery upon Shingles, as there is chances for relapses. It is recommended for any individual particularly aged 50 or above to undertake vaccination, while the younger generations should also pay attention to Shingles which they may possibly be suffered from.
Cervical cancer develops in a woman’s cervix, and almost all related cancer cases are linked to HPV infection. Different genotypes of HPV will lead to diverse diseases, including genital warts (for men and women). Some studies advised that nearly 80% sexually active people will face the threats of HPV infection in their lifetime. HPV infection could incur no significant symptoms, and HPV transmission cannot be avoided even using condoms. HPV Vaccine is prophylactic vaccine that could protect men and women aged 15 or above against HPV infection, allowing the immune system to develop HPV antibodies.
Seasonal influenza is a common respiratory tract infection caused by human seasonal influenza viruses. The influenza viruses could be transmitted through respiratory droplets, and could be latent for 1-4 days. At the onset of influenza, the infected individual will manifest symptoms including malaise, runny nose, headache, coughing, fever and sore throat and etc. In Hong Kong, seasonal influenza is usually prevalent in months like from January to March and from July to August. Quadrivalent influenza vaccine is eligible for individuals aged 6 months or above, and is advised to be taken for comprehensive protection against influenza.
Produced as quadrivalent recombinant influenza vaccine, Flublok® is considered to be the next generation of influenza immunization, and is classified as the competent seasonal influenza vaccination for the 2021/2022 season in Hong Kong. Any individual aged 18 years or above will be eligible for taking the quadrivalent vaccine, and it could yield better protection than the traditional influenza vaccines. Comparing to the standard quadrivalent inactivated influenza vaccine, it is proven to be 30% more effective in preventing flu for the population aged 50 years or above, and the hemagglutinin (HA) antigen per strain is triple to the ordinary vaccine as well. Apart from that, the new vaccine can offer 40% additional cross-protection than standard vaccine, i.e. can still offer protection to the recipients towards virus strains other than those specified in vaccine.
