why do we need covid vaccine? essay questions 300 words
Answers
Answer:
Today marks the start of the World Immunization Week. The COVID-19 pandemic, while draws the world’s attention to the vaccine, also reminds us of the importance of immunization, which saves millions of lives each year.
WHO is working with partners all over the world to accelerate research and development of a safe and effective vaccine and ensure equitable access for the billions of people who will need it. But even with an expedited process, development of a vaccine for COVID-19 will take time.
The ongoing pandemic disrupts routine immunization services in many countries. When immunization services are disrupted, even for brief periods during emergencies, the risk of vaccine-preventable disease outbreaks, such as measles and polio, increase. Further disease outbreaks will also overwhelm health systems already battling the impacts of COVID-19.
Answer:
The vaccines success story gives us hope for the future
Explanation:
The World Health Organization (WHO), working in partnership with both public and private sectors, has a proud history of vaccinology.
By assessing vaccines for global supply, WHO’s groundbreaking Prequalification programme has made possible the deployment of quality-assured, safe and effective vaccines to dozens of countries across the world. This programme gives countries the security and confidence to know that vaccines being purchased meet WHO standards for safety, effectiveness and quality.
The Expanded Programme on Immunization (EPI), created by WHO in the 1970s, has, with the help of UNICEF, Gavi, the Vaccine Alliance, and others, brought lifesaving vaccines to hundreds of millions of children around the world. The immunisation programme is found in every country on the globe. It has the farthest reach and deepest impact of any public health programme. WHO staff have supported governments and health professionals to deliver vaccines where they are needed on the ground. Its success is measured in millions of lives saved each year. Through vaccination, smallpox has been eradicated and polio is on the verge of being defeated
On constant alert, every year, WHO studies influenza trends, to work out which strains are emerging and should be included in the next season’s flu vaccine. And it continually monitors potential signals of pandemic threat.
WHO estimates that in 2018 (the latest year for which estimates are available), 25,000 newborns died from neonatal tetanus, an 88% reduction the figure of 200,000 in 2000.
Global HPV vaccine coverage is increasing. HPV vaccines had been introduced in 106 countries by the end of 2019, representing a third of the global population of girls.
Today, 86% of the world’s children receive essential, lifesaving vaccines, increasing from around 20% back in 1980. This protects them and their communities against a range of infectious diseases, including measles, diphtheria, tetanus, pertussis (whooping cough), hepatitis B and polio. The number of children paralysed by polio has been reduced by 99.9 percent worldwide over the last three decades.
This level of protection comes through a strong global effort to increase vaccine access and affordability, with support in recent decades from new partnerships like Gavi, the Vaccine Alliance - focussing on expanding vaccine availability in the poorest countries - and the Measles & Rubella Initiative.Innovative partnerships have also seen WHO help lead major cholera and yellow fever vaccination campaigns, and have also produced effective vaccines against meningitis and pneumonia, diarrhoea, and the world’s first-ever malaria vaccine currently being piloted in Ghana, Kenya and Malawi.
Ebola
We have known about Ebola since the 1970s, but the disease hit the headlines in 2014–2016 when an epidemic in West Africa killed more than 11 000 people. This epidemic triggered the first human trials of a vaccine against the disease and prompted changes in the way the world responds to outbreaks
To tackle the threat of Ebola, one of the biggest priorities was to fund vaccine discovery, fast-track clinical trials, hasten regulatory approvals and enable manufacturers to produce and roll out an Ebola vaccine. From early testing to trials of the rVSV-ZEBOV Ebola vaccine in Guinea in 2016 took the sum of ten months, a speed unprecedented at the time.
The Government of the Democratic Republic of the Congo (DRC) declared a new outbreak of Ebola virus disease (EVD) in Bikoro in Equateur Province on 8 May 2018. Vaccination began on 21 May.
“I just spent the day out with the vaccination teams in the community, and for the first time in my experience, I saw hope in the face of Ebola and not terror,” said WHO’s Dr Mike Ryan.
When Ebola hit eastern DRCin August 2018, the vaccine was used just days after the declaration of the outbreak. More than 300 000 people were vaccinated from August 2018 to March 2020, which heped to save lives and slowed the spread of Ebola.Looking forward
The Ebola and meningitis vaccines are two of the most exciting developments in global public health in recent history. So too is the evolution of the routine immunization programmes that have so successfully halted the measles and polio outbreaks that once ravaged communities, killing and maiming young children. Pneumococcal and rotavirus vaccines have been successful against some of the most common causes of pneumonia and diarrhoeal deaths. Innovative financing expedited the introduction of the pneumococcal vaccine, enabling it to be launched in 2011, in a world-first, in rich and poor countries simultaneously.
