Some thoughts from an intensive care physician caring for COVID-19 patients in the Bay Area. This is a journal. It is not medical advice, coronavirus education, or public health information. Please use other resources for that. Posts are in reverse chronological order.
One final post on a hodgepodge of vaccine topics.
The current most common COVID-19 vaccines, made by Pfizer and Moderna, require two doses. The booster shot occurs about 3-4 weeks after the initial dose and is necessary to achieve ~95% protection to the virus. Initially, the plan was to distribute half the doses and to keep the other half for the second shot about a month later. Now, several governments and prominent scientists have suggested releasing all the available vaccine immediately so that more people can receive a shot.
I greatly trust and respect some of the voices advocating this second approach. Normally, I would be a stickler for the rules and give the vaccine as it was studied in the trials. Notably, the second method - releasing all the doses - doesn't preclude that; if manufacturing and procurement keep up, we could be able to supply everyone with the second dose by the time a month rolls by.
Although we only have good study data for two doses several weeks apart, in a crisis, we need to think creatively about whether other approaches can achieve better outcomes faster. I don't think answers are clear. We don't know how much partial immunity one gets from just one dose. And we worry that if someone doesn't receive the booster shot, the effectiveness of the vaccine will wane. But I do think a current priority needs to be vaccinating more people faster. Viral spread is exponential, and its prevalence is incredibly high in some communities right now. We need to engage all our tools to slow its spread. If modeling studies show releasing all the doses will tamp down viral spread, then it's worthwhile to entertain. But we still must attempt to get everyone their booster at the appropriate time.
I worry about the ability for developing countries to vaccinate populations at scale. Health care systems need to ensure follow-up for those who need two doses. Robust infrastructure is required to manage the storage conditions of mRNA vaccines. Fortunately, there are some vaccine candidates in the pipeline that may not have such challenging requirements; thus we need to keep pursuing COVID-19 vaccine research. We must not leave developing nations behind.
Lastly, I am pleased to see that the guidelines for vaccine prioritization cover all staff who work with patients and infectious materials. In this blog, I talk a lot about physicians, nurses, and respiratory therapists, but I would be remiss if I did not acknowledge all the other team members who make the delivery of care possible. I worry about the technicians who take X-rays of our COVID patients, the therapist who assesses how they swallow, our housekeeping staff that sanitizes the rooms, and the laboratory technicians who process COVID specimens. They are essential members. They absolutely need to be protected.
Widespread vaccination will be a huge undertaking that will take a while. Until then, we must remember that even if we are vaccinated, we need to continue all the social distancing, masking, hand-washing, and other interventions that help us reduce transmission. 95% effectiveness is wonderful, but not perfect. We also have many unanswered questions like whether vaccinated individuals can be asymptomatic carriers. We cannot let our guard down until this pandemic is fully under control. I worry whether we can reach herd immunity with significant numbers of people declining the vaccine, but I believe that education and time can help improve our numbers. I think that reaching herd immunity will be the most effective way of reducing COVID-19 deaths long term and resuming our pre-pandemic lifestyles.
Never in modern history has there been so much hope, fear, optimism, and sorrow tied to the turning of the year. This global pandemic, which began over a year ago and since visited every continent, has upturned our society to an unimaginable degree. It has taken an unimaginable number of lives. It will leave scars in our personal lives, our communities, and our collective histories. This New Year's I take a moment in memory of those who have died from this pandemic.
When September 11 happened nearly twenty years ago, I struggled to put into words the enormity of such tragedy. I actually wrote every year about it for a decade. Disaster leaves deep impressions. Right now, we are losing more people each day than died on September 11. The numbers, statistics, and scope of what is happening - what has been happening - far exceeds my capacity to comprehend and make sense of it. For me, writing and reflection are ways of trying to, of coping.
Right now, working in the intensive care unit in the Bay Area, I am seeing a situation I have never before witnessed. Even though it is less severe than Italy, New York, or Southern California, and even though I had prepared myself for it, it is unbelievable. Never have I seen such immense strain on our medical system, and never have I seen such true heroism, sacrifice, compassion, and dedication from the caregivers I work with.
There are so many aspects to this disease, the pandemic, and how our lives have changed, and I strive to capture them in this blog. This New Year's, I spend a little time contemplating the medical complexity of the disease, the miracle of such speedy vaccine development, and the humility of how much we still don't know. I think of the individual patients I have cared for, the stress and anxieties of the procedures I've had to do, the heartbreak in the families I've had to call. I think of our successes, the patients who have survived despite all odds. I think of our losses, the death certificates I've had to sign. I think of the comraderie I have with our critical care team, the nurses and respiratory therapists who work side-by-side with me every day, and the extended support team that make my job manageable. I think of our public health system, of those policies that have helped and hindered, of the work yet to be done at a local, national, and global level. I think of the sacrifices made by our families, communities, and businesses for this pandemic, of the postponed hopes and dreams, of the irrevocably changed way of life. I think of the Before Times.
In some ways, today is a day like any other in this pandemic. But I do think, for me at least, there is some value in recognizing even arbitrary occasions. 2020 is over. We look ahead to 2021. Without doubt, the first few months will remain a crisis. But I want it to be the beginning of a new hope, that equipped with a vaccine and renewed resolve, we will again flatten the curve, find a plateau, and rein this disease in. Our communities will adapt, remain creative, and thrive in ways we did not anticipate. We will mourn and cope and nurture and grow. We are facing a global challenge unlike any other in modern history. We did not get it under control in 2020. But I am optimistic that this year we can and will do better, finding humanity, hope, and a new future emerging from the darkest of times.
