In the light of the COVID-19 pandemic, antivaccine sentiments have been on the rise, with a recent seminal study on the development of anti-vaccine views in social media even making its way into Nature Communications. Yet, with the current scientific consensus being in overwhelming agreement over the safety and efficacy of vaccines, many scientists lose their grasp on the fears, concerns, and arguments that the opposition may hold. This paper discusses and evaluates vaccine-hesitant individuals on a socioeconomic, historical, and philosophical landscape. It also provides an analysis of common argumentative patterns and the psychological impact that these arguments may have on undecided individuals. The discussion also explores why anti-vaccine sentiments are on the rise, and how members of the scientific and medical community require a more structured approach to communicating key arguments. This is particularly important if vaccination rates and herd immunity are to be sustained. No longer is it sufficient to win arguments based on a factual and scientific basis, but rather scientists and medical practitioners have to focus on conveying confidence and reassurance on both an informative and emotional level to those with doubts and fears.

Concern about the appropriate role of nonsteroidal anti-inflammatory drugs (NSAIDs) in COVID-19 speculate that NSAIDs, in particular ibuprofen, may upregulate the entry point for the virus, the angiotensin-converting enzyme (ACE) 2 receptors and increase susceptibility to the virus or worsen symptoms in existing disease. Adverse outcomes with COVID-19 have been linked to cytokine storm but the most effective way to address exaggerated inflammatory response is complex and unclear. The Expert Working Group on the Commission of Human Medicines in the UK and other organizations have stated that there is insufficient evidence to establish a link between ibuprofen and susceptibility to or exacerbation of COVID-19. NSAID use must also be categorized by whether the drugs are relatively low-dose overthe-counter oral products taken occasionally versus higher-dose or parenteral NSAIDs. Even if evidence emerged arguing for or against NSAIDs in this setting, it is unclear if this evidence would apply to all NSAIDs at all doses in all dosing regimens. Paracetamol (acetaminophen) has been proposed as an alternative to NSAIDs but there are issues with liver toxicity at high doses. There are clearly COVID-19 cases where NSAIDs should not be used, but there is no strong evidence that NSAIDs must be avoided in all patients with COVID-19; clinicians must weigh these choices on an individual basis.

The emergence of a novel coronavirus and coronavirus disease 2019 (COVID-19) represents a challenge to global healthcare. In the past 20 years, this is the third coronavirus that jumped the species barrier and infected humans. It is highly contagious but associated with low pathogenicity. First identified in Wuhan, China, a city of over 11 million, the disease has since spread to every continent except Antarctica. About 15% to 20% of all cases may be called severe, and it is believed many cases are asymptomatic. The average age of a person with COVID has been reported as 49 years. Worse outcomes are associated with geriatric populations and those with underlying diseases such as cardiovascular, respiratory disorders, and/or diabetes. The coronavirus, like other coronaviruses, is highly contagious and has a latency period of about 14 days. Most patients present with fever and a dry cough, but fever may be absent. Differential diagnosis can be challenging since influenza may present with similar symptoms. Chest radiography or computed tomography may be used to find evidence of secondary pneumonia. Nosocomial infection is of concern, and it has been reported that 3.8% of all cases with COVID-19 in that country involve healthcare workers in China. Most patients have mild disease, and supportive care suffices. A variety of repurposed and investigational drugs are being evaluated. There are currently no antiviral therapies or vaccines, even if many therapies are proposed. Hand hygiene, social distancing, and scientifically sound information are the best strategies at the moment to combat this epidemic.
