This is an extraordinary scientific achievement, but is it safe?
The average vaccine takes approximately 10 years to develop. There are currently two COVID-19 vaccines (Pfizer/BioNTech and Moderna) that will likely be authorized and released to the public within a year of the discovery of the virus. How can a safe vaccine possibly be developed so fast?
These will be the fastest vaccines ever developed, by a margin of years. The next fastest vaccine ever approved for public use was the mumps vaccine, and that took 4 years.
Unfortunately, that speed has made a lot of people nervous. Will the vaccine be safe? Are they skipping steps? How is this process moving so fast?
The best way to minimize risk is to stay informed.
Modern medicine, especially vaccines, have drastically reduced the likelihood of getting infected by a deadly disease in first world countries.
But new strains, unvaccinated people, and other unforeseen factors can still pose a threat, and when an outbreak does occur, disease can spread like wildfire. This is especially true in third world countries, where access to medicine is lacking. These are just eight recent disease outbreaks you need to know about to keep yourself safe.
1. Yellow Fever - Nigeria
Yellow Fever, named for the yellowing effect it causes on skin, is currently spreading in Nigeria's Edo State. The virus is mainly spread through mosquitoes. This outbreak is unusually large in scale and severity, especially considering it's coming at a time of year when many travelers vacation to Nigeria. The World Health Organization (WHO) is not currently recommending any travel or trade restrictions, but they do implore any potential travelers to get vaccinated against the virus.
2. Ebola Virus - Democratic Republic of the Congo
An ongoing Ebola epidemic has been raging in the Democratic Republic of the Congo, with 16 new cases confirmed between December 27, 2018 and January 2, 2019. Ebola is incredibly deadly, causing bloody vomit and internal bleeding, and spreads easily through saliva, bodily fluids, and contact with contaminated surfaces. Since there is no current accredited vaccine for Ebola, travelers are recommended to seek medical advice beforehand.
3. Measles - New York
In 2019, confirmed cases of Measles have hit record highs in New York, at least dating back for a few decades. Measles is the most deadly vaccine-preventable virus, mainly affecting young children and resulting in a red, blotchy skin rash. The virus, which had been mostly irrelevant for decades due to vaccines, has been experiencing a global resurrection propelled by parents not vaccinating their children.
4. Hantavirus Disease - Republic of Panama
Hantavirus disease has been ramping up in the Republic of Panama with 103 confirmed cases during 2018. Infection can progress to Hantavirus Pulmonary Syndrome (HPS), which is a fatal respiratory disease. The disease is primarily spread through rodents, and early treatment has a high success rate of mitigating lasting effects.
5. Typhoid Fever - Islamic Republic of Pakistan
A drug-resistant outbreak of Typhoid Fever has recently been reported in the Islamic Republic of Pakistan. Typhoid Fever is a very serious disease that causes high fever, stomach issues, and in rare cases can result in internal bleeding and death. The illness is primarily spread through contaminated food and water, and the WHO notes that this outbreak highlights the importance of public health measures to prevent such spreads.
6. Candida Auris - US
A type of yeast, Candida Auris is a relatively new infection that has proven difficult to combat. In 2018 there were nearly 500 confirmed cases in the US, and the trend seems to be continuing into 2019. Unfortunately the infection is largely drug-resistant, hard to spot, and prone to outbreak within the healthcare community.
7. Influenza - U.S.
This past flu season, over 80,000 people died from influenza, giving 2017-2018 the highest influenza death toll in 40 years. This was partially a result of the flu vaccine not being as successful as in previous years. People are still strongly recommended to continue getting their yearly flu vaccine to prevent future outbreaks of preventable strains.
8. E. Coli - U.S.
In June of 2018, an E. coli outbreak linked to contaminated romaine lettuce killed 5 people in the US. This strain of E. coli produced life-threatening toxins in the body which caused severe diarrhea, amongst other illnesses. 197 people were affected in total, but luckily the outbreak was contained. Yet another outbreak of E.coli linked to California-grown romaine lettuce ended on January 9, 2019, this time infecting 62 people. Unfortunately, E. coli and Salmonella poisoning is a relatively common occurrence now, especially considering how understaffed the U.S. Food and Drug Administration is currently. The ongoing government shutdown has served to further this problem, making safe oversight of food a serious issue right now.
Ultimately, sometimes you can do all the right things and still get infected with a disease or illness. That being said, with access to modern medicine, it's important to take every possible precaution to avoid preventable outcomes. This means making sure you, your family, and your friends are properly vaccinated, as well as avoiding those who are not. It also means doing your research before traveling to prepare for any possible outbreaks. Should you follow those basic rules, your risk of infection will be at a minimum.
