An 8-ft-high fence may be added to keep deer away from the tick-safe zone. Occupational exposure
Outdoor workers are at risk of Lyme disease if they work at sites with infected ticks. This includes construction, landscaping, forestry, brush clearing, land surveying, farming, railroad work, oil field work, utility line work, park or wildlife management. U.S. workers in the northeastern and north-central states are at highest risk of exposure to infected ticks. Ticks may also transmit other tick-borne diseases to workers in these and other regions of the country. Worksites with woods, bushes, high grass or leaf litter are likely to have more ticks. Outdoor workers should be most careful to protect themselves in the late spring and summer when young ticks are most active. Host animals
Ticks can feed upon the blood of a wide array of possible host species, including lizards, birds, mice, cats, dogs, deer, cattle and humans. The extent to which a tick can feed, reproduce, and spread will depend on the type and availability of its hosts. Whether it will spread disease is also affected by its available hosts. Some species, such as lizards, are referred to as "dilution hosts" because they dont tend to support Lyme disease pathogens and so decrease the likelihood that the disease will be passed on by ticks feeding on them. White-tailed deer are both a food source and a "reproductive host", where ticks tend to mate. The white-footed mouse  is a reservoir host in which the pathogen for Lyme disease can survive.
(1992) (incompetent host for B. burgdorferi and TBE virus) but it is important for feeding the ticks, as red deer and wild boars (Sus scrofa), in which one Rickettsia and three Borrelia species were identified", with high risks of coinfection in roe deer. Nevertheless, in the 2000s, in roe deer in Europe "two species of Rickettsia and two species of Borrelia were identified". Vaccination
No human vaccines for Lyme disease are currently available. The only human vaccine to advance to market was LYMErix, which was available briefly before being pulled from the market in 2002. The vaccine candidate VLA15 is scheduled to start a phase 3 trial in the third quarter of 2022, and other research is ongoing. Multiple vaccines are available for the prevention of Lyme disease in dogs. LYMErix
The vaccine LYMErix was available from 1998 to 2002. The recombinant vaccine against Lyme disease, based on the outer surface protein A (OspA) of B. burgdorferi with aluminum hydroxide as adjuvant, was developed by SmithKline Beecham. In clinical trials involving more than 10,000 people, the vaccine was found to confer protective immunity to Lyme disease in 76% of adults after three doses with only mild or moderate and transient adverse effects. On 21 December 1998, the Food and Drug Administration (FDA) approved LYMErix on the basis of these trials for persons of ages 15 through 70.Following approval of the vaccine, its entry into clinical practice was slow for a variety of reasons, including its cost, which was often not reimbursed by insurance companies.
