Chapter 27, Problem 7A
Summary Introduction
Introduction:
Influenza virus belongs to class V that contains minus single stranded segmented RNA as their genetic material. They are enveloped virus that contains an antigen on their envelope. Influenza virus is the causative agent of flu. They have ability to change their surface antigens by forming a new combination of antigen (mixture of antigen) through the process called as antigenic shift and they also mutate their antigen genes to form new surface antigen. This process is known as antigenic drift

Malaria kills more than 400,000 people a year, mostly children in sub-Saharan Africa. But despite many vaccines being trialled over the years, this is the first to meet the required target. The researchers say this vaccine could have a major public health impact. When trialled in 450 children in Burkina Faso, the vaccine was found to be safe, and showed "high-level efficacy" over 12 months of follow-up. Larger trials in nearly 5,000 children between the ages of five months and three years will now be carried out across four African countries to confirm the findings. Malaria is a life-threatening disease caused by parasites that are transmitted to people through mosquito bites. Although preventable and curable, the World Health Organization estimates there were 229 million cases worldwide in 2019 and 409,000 deaths.…arrow_forward
