![]() ![]() Mumps vaccine had been introduced nationwide in 123 Member States by the end of 2021. Mumps is a highly contagious virus that causes painful swelling at the side of the face under the ears (the parotid glands), fever, headache and muscle aches. By the end of 2021, 81% of children had received 1 dose of measles-containing vaccine by their second birthday, and 183 Member States had included a second dose as part of routine immunization and 71% of children received 2 doses of measles vaccine according to national immunization schedules. Measles is a highly contagious disease caused by a virus, which usually results in a high fever and rash, and can lead to blindness, encephalitis or death. Thirteen countries had included MenAfriVac in their routine immunization schedule by 2021. By the end of 2021, 350 million people in 24 out of the 26 countries in the meningitis belt had been vaccinated with MenAfriVac through campaigns. Before the introduction of MenAfriVac in 2010 – a revolutionary vaccine – meningitis serogroup A accounted for 80–85% of meningitis epidemics in the African meningitis belt. Meningitis A is an infection that is often deadly and leaves 1 in 5 affected individuals with long-term devastating sequelae. This is a proportionally large reduction from 20% in 2019. Since many large countries have not yet introduced the vaccine and vaccine coverage decreased in 2021 in many countries, global coverage with the first dose of HPV among girls is now estimated at 15%. Including 5 new introductions, 116 Member States have introduced HPV vaccine by the end of 2021. Human papillomavirus (HPV) is the most common viral infection of the reproductive tract and can cause cervical cancer in women, other types of cancer, and genital warts in both men and women. Global coverage is 42% and is as high as 78% in the WHO Western Pacific Region, while it is only estimated to be at 17% in the WHO African Region. In addition, 111 Member States introduced nationwide 1 dose of hepatitis B vaccine to newborns within the first 24 hours of life. Global coverage with 3 doses of hepatitis B vaccine is estimated at 80%. Hepatitis B vaccine for infants had been introduced nationwide in 190 Member States by the end of 2021. Hepatitis B is a viral infection that attacks the liver. The WHO Eastern Mediterranean Region and South-East Asia Region are each estimated to have 82% coverage, while it is only 29% in the WHO Western Pacific Region. There is great variation between regions. Global coverage with 3 doses of Hib vaccine is estimated at 71%. Hib vaccine had been introduced in 192 Member States by the end of 2021. Haemophilus influenzae type b (Hib) causes meningitis and pneumonia. This slowdown is likely to continue as countries focus on ongoing efforts to control the COVID-19 pandemic.Ī summary of global vaccination coverage in 2021 follows. Although this is an increase from 17 introductions in 2020, it is well below the number of introductions of any year in the past two decades prior to 2020. Twenty five vaccine introductions were reported in 2021 (not including COVID-19 vaccine introductions). The COVID-19 pandemic and associated disruptions have strained health systems, with 25 million children missing out on vaccination in 2021, 5.9 million more than in 2019 and the highest number since 2009.ĭuring 2021, about 81% of infants worldwide (105 million infants) received 3 doses of diphtheria-tetanus-pertussis (DTP3) vaccine, protecting them against infectious diseases that can cause serious illness and disability or be fatal. Anthony Fauci, head of the National Institute of Allergy and Infectious Diseases, said last week that 75 to 85 percent of people need to get vaccinated to bring the pandemic to heel, let the economy recover and enable people to get back to their daily routines.While immunization is one of the most successful public health interventions, coverage has plateaued over the last decade. The spread of false claims about the vaccines on social media is so troubling because it risks undermining public health efforts. "Part of a larger narrative that they're going to force things onto us to get to this new world order."īaseless claims that the virus was planned and that vaccines will be used to track or control people rank among the most mentioned pieces of misinformation this year, according to Zignal Labs, a media analytics company. "The summary was essentially that this was all part of a larger plan - to use the word 'plandemic' - to either mess with President Trump or as a way to force vaccines," she said. The discredited claims in a video titled "Plandemic" that went viral this summer, thanks in part to conspiracy theorists, echoed falsehoods Koltai had seen earlier in the Facebook groups she follows.
